How do you plan to go about this? The obvious option of just calling
scipy.sparse.issparse() on ufunc entry raises some problems, since
numpy can't depend on or even import scipy, and we might be reluctant
to add such a special case for what's a rather more general problem.
OTOH it might be possible to solve the problem in general, e.g., see
the prototyped _ufunc_override_ special method in:
but I don't know if you want to get into such a debate within the
scope of your GSoC. What were you thinking?
