[Python-Dev] New Import Hooks PEP, a first draft (and req. for PEP #)

[Aahz]

First of all, excellent job!  I've been feeling somewhat frustrated by
the number of directions this discussion has taken, and I'm glad to have
something that's clear and understandable.

One typo nitpick, one real question:

Any reason we can't require importer objects to be new-style classes,
which could then use __new__?  (I vaguely recall some discussion about
this, but it should be documented in the PEP.)
