Is it possible, in principle, to call always the sparse matrix operator
method when it enters an operation with a dense array?
(a .. dense array, b sparse -- a + b calls b.__radd__, b + a calls
The reason I would support this is, that IMHO the higher level object (a
sparse matrix) knows well how to handle the lower level object (a dense
array) in numeric operations, but not vice-versa -- there is already a
number of sparse matrix formats, so the dense array object definitely
cannot understand them all.
