What do we expect the following to print?

ABC?

Do we expect the following to compile?

false + "D"
() + "E"

No, No?

Agree, this is what we see in other (statically typed) languages

It is nice to be able to write println(n + " ...")

I agree that it is nice but this is why we have the strange effects above due to the globally available any2stringad

d - with infix constructors this could be done much cleaner

I'll need to remember to use parens: s += ("B" + "C")

This horrible as val s = "B"+"C" works fine.
