```
query.matching.set_matches(operator: SetOperator, values: &[T], candidate: &T) -> bool
```

Evaluate one operator against its operands.

Ordering compares against the single bound `has_valid_shape` requires;
a malformed predicate that reached here matches nothing rather than
panicking on an absent bound.
