//META: purpose=A `Tuple<int8_t, float, bool>` constructor lowers to a `makeTuple(...)` whose result IR type is `tuple_type(Int8, Float, Bool)` carrying each element's lowered IR type.
//META: intent=expansion
//META: pipeline_stage=lower
//META: warning=Auto-generated. May drift from source. Do not edit by hand.

// Expansion: heterogeneous tuple over mixed precisions. The doc
// does not explicitly list `Tuple`, but tuples are observable in
// IR as `tuple_type(...)` with one operand per element type.
