Yep, this is the crux. types.GeneratorType refers to generator objects,
which in an improper sense are "instances" of a "generator function".

def g(): yield 1 # this is a generator

go = g() # this is a generator object

I want isgenerator(g) == True, but isgenerator(go) == False.

So, what should be the class of g ? Maybe we can keep FunctionType
and don't bother.
