◆ Predicate

using mlir::pdl_to_pdl_interp::PredicateBuilder::Predicate = std::pair<Qualifier *, Qualifier *>

An ordinal predicate consists of a "Question" and a set of acceptable "Answers" (later converted to ordinal values).

A predicate will query some property of a positional value and decide what to do based on the result.
