synopsis:      Type equality evidence you can carry around
description:
    This package provides types and functions to store and manipulate evidence of equality between types.
    .
    To take advantage of kind polymorphism when it is available but not require it, it is split into the following primary modules:
    .
        - @/Type.Eq/@: Types and functions which can be kind-polymorphic if @PolyKinds@ are available, but are specific to kind @*@ otherwise.
    .
        - @/Type.Eq.Higher/@: Kind-monomorphic types and functions of higher kind, up to @* -> * -> *@.
    .
        - @/Type.Eq.Poly/@: Combinators that require kind polymorphism. This module is only available if @PolyKinds@ are available.
    .
    Major required extensions: @GADTs@, @TypeFamilies@ (for @~@), @Rank2Types@, @TypeOperators@
    .
    Optional extensions: @PolyKinds@ (GHC 7.6+)
    .
    Minimum GHC: 6.10
