If only for the fact that our little Haskell community is composed of
about the nicest set of people ever -- I mean, try asking a newbie question on #c sometime -- then Haskell is a great language to learn early. Not only is it great because of it's community, but it's also full of resources -- there are plenty of fun and interesting tutorials to learn with, among the best are Real World Haskell -- it's actually a print book, but you can read it in it's entirety online, give it a google. There's also a nice tutorial called, "Learn you a Haskell for Great Good" (or something like that), I've heard good things about it. By far the best things you can do are subscribe to the Haskell-Cafe mailing list, and get yourself in the #haskell chatroom on freenode.

In fact, it is pretty difficult for anyone to learn in my experience, because it has so many advanced concepts that simply don't exist in other languages, and trying to absorb them all at once will likely be overwhelming. My path into Haskell was roughly C -> Python -> Scheme -> Ocaml -> Haskell, and I think that this has a lot going for it (though for a beginner I would recommend Python over Haskell, and Scheme is suitable for beginners with the right textbooks, e.g. How To Design Programs and/or Structure and Interpretation of Computer Programs).

Theory background and it certainly helps a lot. Still, I think that for a beginner (without any experience with C or anything like that) Haskell would be relatively easy.

As a contrary data-point, at Oxford we teach functional programming (using Haskell) as the first course at the very beginning of the computer science degree. I know several other universities also use FP and Haskell very early on in their CS courses. On the Oxford course about half the students have had significant previous programming experience. There does not appear to be a significant difference in how quickly students with little previous programming experience learn FP compared to those with more programming experience (keep in mind these are young people, not mature students with years of professional programming experience). The point is, it's not at all clear that it's a harder language for beginners. Unfortunately, it rather hard to gather decent evidence about learning on which one could base decisions on the choice of language.

not learning haskell directly, it was un-learning all those patterns and workarounds and so on from imperative/OOP languages.

What I'd be interested to see is how fast beginners pick up haskell compared to imperative language – is it actually hard to learn, or do we just forget how hard it was to learn a new paradigm when we first learned imperative programming. I guess it's rather hard to establish a metric for how fast the learning occurs though.

I disagree, based on seeing my wife learn some Haskell with basically no previous experience programming. It was thrilling to see her learn some concepts almost instantly that it actually took me a while to understand because I had preconceived notions of how programming should work. When I talk about how other programming languages do things she thinks it's stupid. For example, I mentioned that you can actually change the values of variables in most other programming languages, and often have to, and she asked how anything understandable gets written that way. I also noticed that when I kept emphasizing that you can pass functions as parameters to other functions she was getting bored; it seemed that it simply would not have made sense any other way. I see no reason why learning more concepts on top of this foundation should be all that hard for her. - Jake _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@... http://www.haskell.org/mailman/listinfo/haskell-cafe |

I think that all programming languages are hard to learn, because it involves a new way of thinking. It maybe be that Haskell is harder to learn as your *second* language because you have to unlearn things. Especially if your first language was something like C or Python. Additionally, I suspect people forget how hard it was to learn their first language. They get used to the idea that if they know Python, they can learn Ruby with out to much difficulty. But that is only because Python and Ruby share a lot in common. When moving from Python to Haskell, there is simply more to learn (and unlearn). But, if you start by knowing nothing, then it is not clear that you have to learn more to learn Haskell than you would some other language. Also, Haskell may be easier to learn because it's concepts are more 'pricipled' and 'sensible'. Imperative languages tend to allow all sorts of silly errors. For example, letting you use unitialized variables (nearly impossible to do in Haskell). And automatic type casting has burned me so many times. (Especially automatic conversion between floating ponit numbers and integers.) I seldom get off-by-one errors in Haskell, but I do get them in imperative/OOP languages. I suspect that if you don't know any language and want to become a Haskell expert as quickly as possible, then the quickest, straigtest path is to start with Haskell. Also, it depends on what you mean by 'learn' and 'Haskell'. Just as a beginning C++ programmer is not going to learn about templates on day one, a beginner Haskell programmer probably won't be learning type families on day one. Additionally, Haskell includes numerous libraries which are not part of the language itself. Things like parser combinators, pretty printing, applicative functors, etc, are all just libraries. But each of those libraries brings a bunch of new concepts. - jeremy _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@... http://www.haskell.org/mailman/listinfo/haskell-cafe |

Before teaching any data structure course, one MUST learn functional
languages with ADTs. It makes everything so easy to understand. So, it MUST be a first language in every institution. The biggest reason that one should learn functional languages with algebraic data type(ADT)s first is because understanding recursive definitions. If you recursion first, understanding iteration and mutable data structures are dead simple and easy: they are just alternate representation or optimization. However, when you learn while loops and for loops first, your brain gets damaged and a lot of students gets stuck when they first see the Tower of Hanoi, the notorious in-place quicksort routine written in imperative languages, you'll get to think of recursion as some stack blowing up monster that must be unrolled and managed manually. Furthermore, learning data structures in most traditional imperative language literature gives you the impression that linked list and binary trees are brain-fucking spaghetti monsters of memory pointers all the cells, which is a dead simple recursive definition in functional languages with ADTs. Personally, I never really understood what linked list was before I learned ML and Haskell, although I've used doubly linked list in a C++ standard library, which was to me a black box that meets the specification in some huge standard document, for two years. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@... http://www.haskell.org/mailman/listinfo/haskell-cafe |

I believe that from Scheme to Haskell is a natural transition, as I
made the same transition myself. If you grasp the fundamental concepts of Scheme, Haskell seems like a step up. I will describe Haskell in terms of Scheme: # Haskell programs are more correct from the ground up Scheme will let you write (+ 2 "2") and only tell you that it's wrong when it tries to run it ("You can't add a number and a string!"), whereas Haskell won't even let you run it until the types are correct. What some find difficult is ``1'' has type Num a => a, which means "for all types a that are Numbers, a" (or just "all Number types"), e.g. Integer, Double, Rational, etc. But this concept is found Scheme -- in Scheme you have all sorts of number types; ``+'' means "add two numbers". In Haskell, we specify that notion explicitly. # Haskell is half wordy as Scheme Indeed, that is what drew me to Haskell away from Scheme. ## Problem 1 Consider the problem ``Double all the numbers in a list." In Scheme we might solve this problem like so: (map (lambda (n) (* n 2)) '(1 2 3 4) and the result would be (2 4 6). In Haskell, we can write the same: map (\n -> n * 2) [1,2,3,4] and the result would be [2,4,6]. But we take it one step further: map (*2) [1,2,3,4] This means the same as the previous Haskell example. But the formal parameter ``x'' has been tripped away because it is redundant. ## Problem 2 Another problem, ``Given a list of lists, reverse all the lists and double each number in them.'' So in Scheme, we might solve this like so: (map (lambda (list) (reverse (map (lambda (n) (* n 2)) list))) '(1 2 3 4 5)) In Haskell, the same solution is rendered thusly: map (reverse . map (*2)) [1,2,3,4] The ``foo . bar'' is equivalent to (\x -> foo (bar x)), or, in Scheme (lambda (x) (foo (bar x))). It's just that we have stripped the redundant formal parameters. ## Problem 3 Suppose our problem is ``Multiply the first three items of a list''. Our Scheme solution might be: (define (first-three-sum list) (* (car list) (cadr list) (caddr list))) In Haskell, we may write (admittedly, a better way to render this might be: firstThreeSum = sum . take 3): firstThreeSum (x:y:z:_) = x * y * z Here I have demonstrated pattern matching, a powerful and oft-used feature of Haskell for deconstructing a data structure, like a list or a tuple, based on a pattern. I'll abruptly stop here before I write a whole article. I'll summarize by saying that Haskell is the next step, a natural progression where things that you know all too well from Scheme become easier, and safer. The stuff described here is just the tip of the ice burg, of course. I wish that I had learned Haskell as my first programming language! Haskell takes a lot of effort to learn, but gives back in equal amounts. It is a rough ride to learn any programming language. If you think otherwise, you are not learning, or are learning wrongly. 2009/7/14 Simon Peyton-Jones <simonpj@...> > > Haskell is a great language! Check out haskell.org.

Such a 'functional first' approach is the natural way to start a background on programming. Look at the hardware side, for instance: which of the following kinds of digital system is taught first: combinatorial (eg. nand, nor gates) or sequential (eg. flip-flops)? The first, of course, because such circuits are functional (no state, no feedback). More recently I had a go at teaching Haskell to beginners in a non CS context (to arts students studying musicology, actually). If you are interested, have a look at the slides available from the course's URL: www.di.uminho.pt/~jno/html/ipm.html#sec:mp (Under Acrobat some scores will start playing music once you click the "pin" symbol on the right.)
