// Variadic heterogeneous type packs — step 3 complex smoke.
//
// Three-element pack with `$args[2]` (the third element) used in
// the return-type position. Confirms:
// - Multi-arg packs index past the zeroth element correctly.
// - Three distinct call shapes get three distinct monos.
// - The return-type slot is correctly substituted per-mono so
//   the inferred caller type matches what the body actually
//   returns (string / i64 / bool here).
