Most functions are:

def func(args):
    body
    return result

Generators are:

class func(args): # okay, you can't shortcut it like that, give it an
__init__ method
    def do_stuff(self):
        body
        yield results one by one

I don't know that anything would be gained by having a different
function declaration statement/attribute, but maybe this is something
that would benefit from a code comment (which, as far as I'm
concerned, is as much a part of the function signature as the coded
parts are).
