But this seems like an easy case to catch, and is very mathematically
natural and user-friendly, esp. for going back and forth between
matrix stuff and calculus stuff like one often does in sophomore-level
courses. Certainly we shouldn't *require* a tuple or list as input -
that would be silly, I agree.
