The current parser can't deal with "NAME ':'" as a syntax rule,
because expressions also start with NAME.
I also don't like that you have to repeat the function name.
And this would hide the "important" decorators (e.g. classmethod)
amongst a large collection of metadata (unless you want to combine
this with the "def foo [classmethod] (cls, a, b, c):" syntax.
