def add(a: int, b: int) -> int: return a + b

is this surprising to you ?

Yes, since I was a kid.

My first real computer was an RPN calculator.

Also one of my first programming textbooks back then used an educational PL which allowed multiple return values (late 80s).

I think in terms of data flows and circuits, so it’s natural for me.
