Running python2.6 with the -3 option, you get 6 warnings about callable():

On my Mac, I also get about 30 warnings about dict.has_key. By the way,
what are you supposed you use in py3k instead of callable?

Either "try: foo(); except TypeError: ...", or "if hasattr(foo,
'__call__'): foo()".

IMO the warning can be removed. The 2to3 tool can easily migrate any
callable(spam) to hasattr(spam, '__call__').

I can't reproduce this with Python 2.6 (final) on Windows and Python
2.6.2 on Linux. I guess that this was fixed before the final release.
Closing as "fixed".
