trait Predicate extends Product with (Cursor) => Boolean

A reified predicate over a Cursor.

Query interpreters will typically need to introspect predicates (eg. in the doobie module we need to be able to construct where clauses from predicates over fields/attributes), so these cannot be arbitrary functions Cursor => Boolean.
