Module: Data.TypeLits
Copyright: (c) 2018 Iris Ward
License: BSD3
Maintainer: aditu.venyhandottir@gmail.com
Stability: experimental

This module provides the same interface as "GHC.TypeLits", but with
naming conflicts resolved in favour of this package.  For example,
'(<=)' resolves to the kind-polymorphic version from "Data.TypeNums".

If you are only working with type-level numbers, import "Data.TypeNums"
instead.  This module is purely for convenience for those who want to
use both functionality from "GHC.TypeLits" and functionality from
"Data.TypeNums".
