Another formatting question: function types

Hi All,

I wanted to take the community's temperature on how they prefer to see
function types formatted. I have three questions.

1. Do you want spaces around the => or not? Here is with spaces:

(String, Int) => Unit

Here is without:

(String, Int)=>Unit

2. If a type has arity 1, do you want parens around it or not? Here it
is with parens:

(String) => Unit

Here it is without:

String => Unit

3. Lastly, anything else you like to see?

Thanks.

Bill
