Tuple expressions

Tuples group a small, fixed set of values without declaring a new type. They are useful for local results and short-lived data shapes.

Tuples can be named or positional. Both projections are available.

val tuple = (a: 42, b: 2)
Console.WriteLine(tuple.a)      // named
Console.WriteLine(tuple.Item1)  // positional

Tuple types and their element-name rules are documented in Types and unions.
