// Failable `or` rejection (ERR step E2.4a): the value-terminator form
// (`lhs or value`) requires a value-carrying failable LHS — a pure failable
// (`-> !`) has no success value to fall back to, so `or value` is rejected
// (use `catch` to absorb the error). The positive cases live in
// `examples/231-failable-or.sx`.
