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.

Antoine.
