Just to be clear, I wasn't suggesting forcing parens for class definitions.  Rather make them optional for functions!

This seems to me to break a symmetry with class definitions.  I assume this is just a hold off from C, perhaps there is a non-historical reason tho.

I believe in the past we've forced parens in list comprehensions to create a symmetry between comprehensions/generator expressions.  Why not for this?
