I think the issue is that this is a borderline case.
Generally speaking I prefer exceptions plus long-and-tedious error
messages, because it reduces the number of "why does your silly code
crash" bug reports. Asserts I restrict to invariants in my code.
However, any interface that's designed to be used in a tight inner loop
should use asserts instead (plus a really big warning in the docs!).
Something like vector subscripting is a good example.
I'm not sure which this is.... although any usage inside a loop would
likely be trivial compared to any mutating operations on the polynomial?
