Arrays and collections

The released compiler supports managed arrays of its supported element types.

int[] values = new int[5];
string[] names = new string[3];

values[0] = 42;
int first = values[0];
int length = values.Length;

Array counts must be int; void[] is invalid. Elements are zero/default initialized. Arrays are mutable reference types, so assignment and passing to a method retain the same underlying array. Out-of-range access is a runtime error.

Arrays may contain primitive values, strings, enums, and classes:

Pair[] pairs = new Pair[2];
pairs[0] = new Pair(9, "pair");

The current release has no built-in List<T>, map, set, or generic collection. Use arrays and explicit counters until the standard library provides them.
