Ok, then I'll pass that on to the (sparse) scipy folks.
Are there any alternative to np.dot you are aware of? Is
ndarray.__mul__ supposed to work with sparse matrices? AFAIK scipy
does not provide a scipy.sparse.dot function and spmatrix.dot only
allows for "multiplication from the rhs" (ok.. one could directly call
__rmul__ but that's ugly).
