Comment:
There is a TODO in that there isn't a good way to create a matrix over
`ZZ` union `oo`. By default, it coerces into the infinity ring, and
explicitly working over the symbolic ring, I couldn't get the equals check
to work. I think we'd need a ring for a base ring union infinity as a
default coercion.
