I know ipython is a very different beast than numpy for this
discussion (no C code at all, but extensive, invasive and often
obscure use of the stdlib and the language itself).  But FWIW, I have
convinced myself that we will only really be able to seriously tackle
the 3 transition when we can ditch 2.5 compatibility and have a tree
that runs for 2.6 only, with all the -3 options turned on.  Only at
that point does it become feasible to start attacking the 3 transition
for us.  We simply don't have the manpower to manage multiple source
trees that diverge fully and exist separately for 2.x and 3.x.

Cheers,
