I've also thought about that. I do not like the fact that I then need to educate the other developers about minute details of the import machinery just so they can add code to the library. I'm currently the only developer doing actual work in Python and would like to make the transition as painless as possible.

Hmm, I like the idea but sadly it doesn't look very IDE-friendly.

Thanks for your tips!
