Ideally, cython would be used for the boring stuff, and we keep C for the low-level machinery, but the current code don't cleanly separate those two layers (there is simple C API for indexing, ufunc, etc...). I am concerned about cython making that difference even more blurry. David > > -n > > -- > Nathaniel J.
