I wonder if porting them from Python to Cython (the new pyrex) to
get the good and robust C implementation would be a good solution.
There was a huge discussion about that on the scipy list about a
year ago, when they were discussing GSoC"08 work and whether to use
Cython there .. http://mail.scipy.org/pipermail/scipy-dev/2008-April/008922.html
. Actually don't know where that ended, how much Cython code they
nowadays have there?
Granted those vector classes may be simple enough to be easily
doable in raw c too .. but certainly the ease of making classes and
methods in normal py style in cython seems tempting to me, porting
from py to cy is not much work. Haven't written it myself yet, but
Pyrex has seemed to work well for Soya3d since many years already,
and am considering using Cython now for wrapping stuff in another
project for work.
Don't have a strong opinion on that, nor know really what things in
pygame it might suite best, but just mentioning as a possibility. http://www.cython.org/
-1 on Cython/Pyrex from me.
FWIW I plan to implement simple/fast vector, matrix and quat types in
C for my lepton project in the coming months. If nothing has
materialized before then, I'd be happy to donate them to pygame.
