I really wish swift used the concept of tuples **exclusively** for all purposes that involve parentheses, as well as dividing tuples into two categories: - Bare tuples, which do not have labels. - Rich tuples, which do. As a consequence, here's a list of statements that would become true: - All functions take exactly one parameter, which is a tuple. - All closures (a.k.a. function pointers) take exactly one parameter, which is a bare tuple. - All functions return exactly one parameter, which is a tuple. - Pattern matching is done on a single bare tuple using a single bare tuple pattern. The currently ongoing proposal to make a single-element tuple auto-flatten would work extremely well with this idea, by making all these changes completely backward-compatible.
