  Description: |-
    Derive KnownNat constraints from other KnownNat constraints
     A type checker plugin for GHC that can derive "complex" KnownNat
     constraints from other simple/variable KnownNat constraints. i.e. without
     this plugin, you must have both a KnownNat n and a KnownNat (n+2)
     constraint in the type signature of the following function:
     .
     f :: forall n . (KnownNat n, KnownNat (n+2)) => Proxy n -> Integer
     f _ = natVal (Proxy :: Proxy n) + natVal (Proxy :: Proxy (n+2))
     .
     Using the plugin you can omit the KnownNat (n+2) constraint:
     .
     f :: forall n . KnownNat n => Proxy n -> Integer
     f _ = natVal (Proxy :: Proxy n) + natVal (Proxy :: Proxy (n+2))
     .
     The plugin can derive KnownNat constraints for types consisting of:
     .
      * Type variables, when there is a corresponding KnownNat constraint
     .
      * Type-level naturals
     .
      * Applications of the arithmetic expression: +,-,*,^
     .
      * Type functions, when there is either:
     .
     1. a matching given KnownNat constraint; or
     .
     2. a corresponding KnownNat<N> instance for the type function
     .
     To use the plugin, add the
     .
     OPTIONS_GHC -fplugin GHC.TypeLits.KnownNat.Solver
     .
     Pragma to the header of your file.
