It isn't hugely important, but with sys._getframe() unlikely to appear during runtime, the following may make more sense:
if hasattr(sys, '_getframe'): def currentframe(): return sys._getframe(1) else: def currentframe(): pass currentframe.__doc__ = "Return the frame of the caller or None if this is not possible."
I considered that but found the docstring thing ugly.
(Oh, and there's a typo in the docstring...)
Thanks. -- Regards, Benjamin
