// Error-set value + `==` typing rejections (ERR step E1.1):
//   - an `error.X` literal must name a tag that is in the destination set,
//   - an error-set value compares only with an `error.X` tag or another
//     error-set value; comparing to a raw integer is a type error
//     (coerce with `xx` to compare the raw id).
// The positive cases live in `examples/217-error-sets.sx`.
