There are so many things going on here it's getting difficult to keep
track of them all! Not only Victor's stuff, but also Mario's patches
for faster multiplication, and for subquadratic division. And it might
be interesting to experiment with subquadratic int <-> str conversion as
well.
I'm wondering whether it would be worth starting a new
"py3k_long_optimization" branch, so that we can get some of the obvious
stuff in and start experimenting properly with the rest.
Christian, you're the expert on this: any thoughts? Is it possible to
set up a new svn branch so that it's easy to merge from the py3k branch,
or is svn merging only really possible from the trunk? I'm happy to set
things up and take care of doing regular merges, if you can give me some
pointers.
(If not, maybe it's time for me to learn how to use git/hg/bzr. I've
used darcs quite a bit before, so the concepts aren't totally alien to
me, but I haven't found time to learn other systems yet.)
