Bind in ReScript (not to import JS, but to bind multiple Option or Result)

On this note, while more specific to the option case, also worth knowing about Array.filterMap and Array.keepSome

Array.filterMap([1, 3, 5, 7], n => n > 4 ? Some(n) : None)
// [5, 7]

Array.keepSome([Some("a"), None, Some("b")])
// ["a", "b"]
