GHC.Generics.Lens

Description

Note: `GHC.Generics` exports a number of names that collide with `Control.Lens`.

You can use hiding or imports to mitigate this to an extent, and the following imports, represent a fair compromise for user code:

     import Control.Lens hiding (Rep)
     import GHC.Generics hiding (from, to)

You can use `generic` to replace `from` and `to` from `GHC.Generics`, and probably won't be explicitly referencing `Rep` from `Control.Lens` in code that uses generics.

This module provides compatibility with older GHC versions by using the generic-deriving package.
