Somewhat related to that last point:
could an array grow an `inv` method?
(Perhaps returning a pinv for ill conditioned cases.)
Here are the primary things that make matrices convenient
(particular in a teaching setting):
* (partly addressed when `dot` method added)
** (could be partly addressed with an `mpow` method)
.I (could be partly addressed with an `inv` method)
.H (currently too controversial for ndarray)
Some might also add the behavior of indexing,
but I could only give qualified agreement to that.
