// Value-carrying `catch` rejection (ERR step E2.1b): when the failable LHS
// carries a value, a non-diverging catch handler must produce a value of the
// success type — a value-less (void) body is a type error (otherwise the
// success and error paths couldn't merge to one value). Diverge instead
// (`return` / `raise`) or yield a value. Positives: `examples/229-value-failable-consume.sx`.
