That's OK with me: as long as the core remains fully functional under
2.3, I'm perfectly OK with the idea that extensions may require 2.4 to
work.  I'd prefer not to have extensions that depend on 2.5, but even
that could be OK if a really good one is a pain to write under 2.4.

We just want to give 2.3 users the 'basic' ipython, which I think will
satisfy the needs of most.
