ghc-typelits-presburger augments GHC type-system with Presburger Arithmetic Solver for Type-level natural numbers. This plugin only work with GHC builtin operations. To work with those of singletons package, use ghc-typelits-meta and/or ghc-typelits-presburger instead.

Since, integration with singletons package moves to singletons-presburger.

You can use by adding this package to build-depends and add the following pragma to the head of .hs files:
