In the purest mathematics that I have seen, they also take only one value.
After that, it's all just syntax, so who cares, right? Likewise, I have
met plenty of mathematicians who will generalize functions to returning
more than one value for their proofs. It's all syntax, and there is no
reason not to take advantage of the clarity it can provide.
