// A struct constant with a NON-serializable initializer field (a call, a
// runtime read) keeps INLINE RE-LOWERING semantics: the initializer is
// evaluated AT EACH USE. This is the documented contract for this class
// — `CALL.r` may differ between reads and side effects run per use.
// For evaluate-once semantics use `NAME :: #run f();`.
