[issue30071] Duck-typing inspect.isfunction()

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

__code__ is not enough for quacking as a function. Different code can expect other function attributes (for example __name__, __qualname__ and __module__).

See also issue8488. inspect.isroutine() and inspect.ismethoddescriptor() return True for some descriptors, but they don't quack good enough for pydoc.
