decidable-0.2.1.0: Combinators for manipulating dependently-typed predicates.

This library provides combinators and typeclasses for working and manipulating type-level predicates in Haskell, which are represented as matchable type-level functions k ~> Type from the singletons library. See Data.Type.Predicate for a good starting point, and the documentation for Predicate on how to define predicates.
