type-equality: Type equality, coercion/cast and other operations.

[ bsd3, data, dependent-types, library ] [ Propose Tags ]

In the presence of GADTs, sometimes a proof is needed that two types are equal. This package contains an equality type for this purpose, plus its properties (reflexive, symmetric, transitive) and some useful operations (substitution, congruence, coercion/cast). It also contains a type class for producing equality proofs, providing some form of decidable equality on types.
