Incidentally, if the reason you're running into this issue is because
you've somehow lost the original .py file and have only the .pyc file,
you can use decompyle to get a pretty good restoration of the original
source.  I don't think decompyle is available anymore (except as a paid
service), but you should be able to find an old copy in someone's
archive somewhere (and it should work well on 1.5.2 .pyc files).
