[issue7006] The replacement suggested for callable(x) in py3k is not equivalent

[Milko Krachounov]

Milko Krachounov <python at milko.3mhz.net> added the comment:

My suggestion is not only unreadable, but wrong. It's even less accurate
than hasattr(x, '__call__'), as it doesn't look in all the classes in
the MRO. Using isinstance(x, collections.Callable) should probably be
the correct replacement for 2to3 and situation where checking this is
really needed, as it does look for __call__ in the whole MRO.
