Dynamic pattern matching attempt
{-# LANGUAGE TypeSynonymInstances, FlexibleInstances, MultiParamTypeClasses, GADTs, FlexibleContexts #-}
module SimplyDifficult where
-- This thing demonstrates dynamic pattern unification,
-- however the examples are too simple to verify that the unifier is
-- working correctly.
-- There were also a thing or two that were way too hard to implement.
-- I've omitted them.
module SimplyEasy where
-- From the paper: http://strictlypositive.org/Easy.pdf
-- An attempt to add case -statement.
-- Fails on typechecking a case.
