Replying to [comment:1 jason]:
> Do you think it might be better to add the positive phrasing,
m.is_singular(), rather than the negative nonsingular version?
I had that thought. It would then no longer be an alias, which means (a)
the documentation could be separate from invertibility, and (b) it would
only need to be done once (`is_invertible` is defined twice). Does it
work for users/students? I like to '''define''' nonsingular, but there is
no real good reason for that, I guess. What's your preference?
