Is any pypy dev interested in (a)? I really don't think there is, so we might continue discussing the road to take. For games and for a lot of matrix processing (AI, encription) numpy is good enough. Matplotlib could be easily ported to pypy, just by dropping some features (AGG and part of the freetype support code). FFT, blas and a lot of pieces of scipy just need a pointer to data só they should work (if there is a ctypes wrapper). Cython is being worked on so when that is ready parts of sage will just run, as everything else using cython. Why not move more of scipy to cython/ctypes? That is what you guys want for the future, and then it would not make anyone have to work on something they have no interest in. -- Leonardo Santagada _______________________________________________ pypy-dev mailing list pypy-dev@python.org http://mail.python.org/mailman/listinfo/pypy-dev
