Correct, I am not sure where this might go in. It seemed like a NumPy array
operation (touching array elements rapidly etc. can also be added for
similar functionalities other than solve) hence the NumPy list. But of
course it can be pushed as an exclusive SciPy feature. I'm not sure what
the outlook on np.linalg.solve is.


> How much is a noticeable slowdown? Note that we still have the current
interfaces available for users that know what they need, so a nice
convenience function that is say 5-10% slower would not be the end of the
world.

the fastest case was around 150-400% slower but of course it might be the
case that I'm not using the fastest methods. It was mostly shuffling things
around and using np.any on them in the pure python3 case. I will cook up
something again for the baseline as soon as I have time.
