Named Tuple Type (Labeled)

Tuple types can include optional labels or names for each element. These labels are for readability and tooling assistance, and do not affect the operations you can perform with them.

type T = string;
type Tuple1 = [T, T];
type Tuple2 = [a: T, b: T];
type Tuple3 = [a: T, T]; // Named Tuple plus Anonymous Tuple
