    //
    // Values of any of the above types can be assigned as "var" or "const"
    // to allow or disallow changes (mutability) via the assigned name:
    //
    // const a: u8 = 5; // immutable
    // var b: u8 = 5; // mutable
    //
    // We can also make error unions or optional types from any of
    // the above:
    //
    // var a: E!u8 = 5; // can be u8 or error from set E
    // var b: ?u8 = 5; // can be u8 or null
