[Numpy-discussion] Deprecate matrices in 1.15 and remove in 1.17?

Hi Ralf,

Sorry not to have recalled the previous thread.

Your point about not doing things in the python 2->3 move makes sense;
handy for me is no reason to give users an incentive not to move to
python3 because their matrix-dependent code breaks.

It does sound like, given the use of sparse, a separate package - or
perhaps (temporary) inclusion in scipy - would be the way to go. In
turn, collecting as much of the matrix tests and work-arounds together
in the `matrixlib` would be the right first step.

And, even better, to collect thoughts in a NEP.  Now if only I had not
written this while procrastinating on other things...

All the best,
