Beats me.  However, this is fixed in Python 2.3.

Yeah, but that won't work if you're importing the module, eh?  ;-)

So you could do (untested, off the top of my head):

def myname():
    try:
        name = __file__
    except NameError:
        if __name__ == '__main__':
            import sys
            name = sys.argv[0]
        else:
            raise DontKnowWhatTheHellTheNameIs

    return os.path.abspath(name)

Cheers,
