All very well, but inspect.getmembers is implemented using dir() /now/,
and doesn't return all of the methods in the /currently-existing/
versions of Python that the OP wants to use. It isn't an appropriate
solution, unfortunately.

Well, that's certainly true.

The dir(self.__class__) works OK for me, since they're all wacky custom
classes. I would still like to know why, in Python 2.1, none of the methods
show up for when using dir() (or __dict__) on an instance of the class. It's
really quite odd :)

>>> len(dir(blah)), len(dir(blah.__dict__))
(24, 24)
>>> len(dir(blah.__class__)), len(dir(blah.__class__.__dict__))
(49, 49)

Thanks to the various people who helped me out again :)
