-- `rng` is a short-form alias for the canonical `range` builtin.
-- nlp-engineer rerun8 reached for `rng` first when working with
-- numeric ranges; the 5-char canonical name paid a repeated token
-- tax in tight scripting code. The alias resolves to `range` after
-- parsing, so both forms below are behaviourally identical on every
-- engine.
main>n;xs=rng 0 10;sum xs
via-canonical>n;xs=range 0 10;sum xs
-- Nested form: `rng` as a sub-call inside another builtin's args.
nested>n;sum rng 0 10
