That's interesting to hear; I haven't been following PySparse
development for a while. Around the time of the Numeric -> SciPy core
transition, I took a snapshot of PySparse, patched it to compile with
NumPy and added it to the sandbox, with the idea of using it as a
basis for improvements to (or even a re-write of) the scipy.sparse
module. But we decided to keep the existing scipy.sparse matrix types,
and when I came to add the new list-based lil_matrix type, it turned
out to be easier to design it from scratch rather than port PySparse's
ll_mat.c code to Python.
So I see no reason to keep the pysparse snapshot in the sandbox any
longer. I've actually been meaning for a while to propose that we
delete it from the tree...
