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."
(Oh, and there's a typo in the docstring...)
Cheers,
Nick.
