Mark Dickinson <dickinsm at gmail.com> added the comment:
The key difference between the func_del function and the instance C() is that func_del is a (non-data) descriptor in addition to being callable, while the instance C() is not. That makes func_del usable as a method.
If you define C as follows, you'll see the behaviour you expect:
class C:
def __call__(self, *args, **kwargs):
print("call", args, kwargs)
def __get__(self, obj, objtype=None):
return MethodType(self, obj)
Useful reference for descriptors: https://docs.python.org/3/howto/descriptor.html
I'll close here, since this is neither a bug nor a feature request.
