template-haskell-2.16.0.0: Support library for Template Haskell
Safe HaskellSafe
LanguageHaskell2010

Language.Haskell.TH.Lib.Internal

Description

Language.Haskell.TH.Lib.Internal exposes some additional functionality that is used internally in GHC's integration with Template Haskell. This is not a part of the public API, and as such, there are no API guarantees for this module from version to version.
