In Python 2.1, sys._getframe([depth]):
Return a frame object from the call stack. If optional integer depth is
given, return the frame object that many calls below the top of the stack.
If that is deeper than the call stack, ValueError is raised. The default for
depth is zero, returning the frame at the top of the call stack.
This function should be used for internal and specialized purposes only.

In older versions, a try/catch and lot of play with
the traceback object lets you do similar things, but
it's even more obviously 'black magic':-)
