GHC.TypeLits.Internal

Description

DO NOT USE THIS MODULE. Use GHC.TypeLits instead.

This module is internal-only and was exposed by accident. It may be removed without warning in a future version.

(The technical reason for this module's existence is that it is needed to prevent module cycles while still allowing these identifiers to be imported in Ord.)

Since: base-4.16.0.0
