Just curious (and a bit off topic), what exactly does warrant a warning in Python? I've been messing around with it for a couple years (since shortly before 3.1, and always on 3.x) and I'm pretty sure I have yet to see a warning for anything. Which I suppose could be counted as a good thing...

We don't really have a well-defined policy, except for one warning category: DeprecationWarnings, whose purpose are quite clear. But they are now silenced by default :-)

Generally, warnings are not easy to deal with for the end-user, so we are reluctant to add any. We'd rather document annoyances and pitfalls; and, moreover, we try to design our APIs so that they don't have unexpected effects.

Regards

Antoine.
