Hello!

I'm having a bit of a trouble getting the deprecation warning for backquotes repr right. Neither the astfor* functions in Python/ast.c nor the node structures have access to the filename.

On a related note, every time you start a Python interpreter with -3 you get 8 instances of

warning: callable() not supported in 3.x

They come from copy_reg.py:pickle/constructor. Py3k has a hasattr('call') there. Am I correct that for Py2, that must be

hasattr(object, 'call') or isinstance(object, types.ClassType)

? Or are there other callable objects without a call method?
