Parameter passing

Parameters in NPL are passed by value for all types, except for protocols.

Trailing commas

NPL supports trailing commas wherever parameters can be specified.

function trailingCommas(
    a: Number,
    b: Number,
    c: Number,
) returns List<Number> -> {
    return listOf(
        a,
        b,
        c,
    );
};

protocol[p] Trailing(
    var a: Text,
    var b: Text,
) {
    permission[p] commas(
        c: Text,
        d: Text,
    ) { };
};
