Hello, everyone.
Can someone please explain to me multiple return values? Not what it
does, I understand that much, but what is this feature for? In what
situations is it useful?
It's useful in situations where several values are the result of a
single computation. A simple example of this situation is the quotient
and remainder of an integer division.
There's also a more philosophical argument for them which is that, for
symmetry, functions should be able to produce multiple results since
they may consume multiple inputs.
