operator > method
- Expectation error
Returns a new validator that will return the error message if the validation fails
This is Sugar, it allows for more concise validator composition.
The underlying child's error code (and data) are preserved and propagated into the
provided error (only the message is replaced). See docs/expectation_codes.md for the
canonical list of built‑in codes.
Implementation
IValidator operator >(Expectation error) => withExpectation(this, error);
