Tuples are used for passing arguments to and from a function. Common

That's from Mesa, the Xerox PARC language of the 1970s.
Mesa used tuples for subroutine arguments in a very straightforward
way. Every function took one tuple as an argument, written as
parameters
in parentheses separated by commas.
Most statically typed functional languages seem to do pretty much the
same: uncurried functions really take a tuple as single argument
rather than multiple arguments, using pattern matching to make it look
like multiple arguments. Then again, most of them seem to default to
curried functions these days, which is nice.
