Ah, yes, someone else has already made a patch here: http://bugs.python.org/file39090/callable.diff This is the issue: http://bugs.python.org/issue23990 Would you add your thoughts there?

So propose a patch for callable() along these lines. It'll have to be C code.

Yes indeed, that's one way but I wouldn't want to monkeypatch the `callable` builtin. People wouldn't expect that library would even dare monkeypatch builtin.

Proxies are a bit of a pain. But you can create your own callable function.
Something like (untested):
def callable(obj): try: func = obj.__call__ return True except AttributeError: return False
