![]() Around that, we organize a set of simplification procedures and their correctness proofs: we include procedures that can unfold calls to user-defined chains, simplify match expressions, and construct approximations removing unknown or unwanted match expressions. This semantics is tailored to the specifics of the filter table and supports arbitrary match expressions, even new ones that may be added in the future.
