Enum Operator

    Equals(Literal),
    Range {
        lower: Bound<Literal>,
        upper: Bound<Literal>,
    },
    GreaterThan(Literal),

    Contains {

        case_sensitive: bool,
    },
    IsNull,
    IsNotNull,
}

Comparison/matching operators over untyped Literals.

In accepts a borrowed slice of Literals to avoid allocations in the common case of small, static IN lists built at call sites.
