I was focused on the `matrix` object.
For this object, an initial asarray is all it takes to use array code.
(Or ... not?)  And it is a view, not a copy.

I don't have the background to know how scipy ended up with
a sparse matrix object instead of a sparse array object.
In any case, it seems like a different question.
