libghc-ghc-typelits-natnormalise-prof 0.7.6-1 (amd64 binary) in ubuntu lunar

 A type checker plugin for GHC that can solve equalities and inequalities
 of types of kind @Nat@, where these types are either:
 .
   * Type-level naturals
 .
   * Type variables
 .
   * Applications of the arithmetic expressions (+,-,*,^).
 .
 It solves these equalities by normalising them to sort-of SOP
 (Sum-of-Products) form, and then perform a simple syntactic equality.
 .
 For example, this solver can prove the equality between:
 .
 (x + 2)^(y + 2)
 .
 and
 .
 4*x*(2 + x)^y + 4*(2 + x)^y + (2 + x)^y*x^2
 .
 Because the latter is actually the SOP normal form of the former.
 .
 To use the plugin, add the
 .
 OPTIONS_GHC -fplugin GHC.TypeLits.Normalise
 .
 Pragma to the header of your file.

 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
