Hi,
Several tests didn't pass due to the recent changes

Looks to me like the __rmul__ operator for sparse matrices needs to be
called in these cases which have in common the form
matrix * sparse
Right now conversion to asmatrix is called on the rhs. Hmmm, I didn't want
to forgo constructs like
matrix * [[1],[2]]
I wonder what asmatrix(sparse) is doing as it doesn't seem to raise an
error. Also, how does one call spmatrix, it doesn't seem to be a standalone
function, nor do I see how it gets into the test class as the test class
doesn't subclass anything?
SVN seems to be down, so there is nothing I can do at the moment.
