I love it when it works!

You'll never satisfy everyone. Personally, I write too much code
without docstrings, so I find the complaints about missing docstrings
annoying. I guess my preference would be to have the default mode ony
complain about things that have a high probability of being *coding*
errors -- undefined names and the like. I forget if you're checking
string formatting conformance yet -- that would also be useful.

Unfortunately the typical newbie doesn't have access to pychecker

Sure! You can add a FAQ entry yourself -- the password is "Spam".

Python version compatibilities would be an interesting area to
I would like PyChecker to use a fundamentally different way of
scanning modules. I believe that it currently imports the module and
then scans the module's __dict__ for classes and functions, and
analyses their bytecode. That's fragile, dangerous (if you don't know
what a module does you may not want to import it), and sometimes
causes spurious errors, like when I have this at the global level:
and no other references to the module foo anywhere in the code... You
get an error about an unused foo module.

I've approved it, but in general, we'd all prefer it if you submitted
patches to the SourceForge patch manager -- that's what it's there
for. If you want to discuss it here, post a URL. :-)
