Description

Lenses, Prisms, and Traversals for working with Template Haskell.

Beware that the API offered in this module is subject to change, as it mirrors the API exposed by the template-haskell package, which frequently changes between different releases of GHC. An effort is made to identify the functions in this module which have different type signatures when compiled with different versions of template-haskell.
