</p><p>You can use hiding or imports to mitigate this to an extent, and the following imports,
 represent a fair compromise for user code:
</p><pre> import Control.Lens hiding (Rep)
 import GHC.Generics hiding (from, to)
</pre><p>You can use <code><a href="Generics-Deriving-Lens.html#v:generic">generic</a></code> to replace <code><a href="/usr/share/doc/ghc-doc/html/libraries/base-4.6.0.1/GHC-Generics.html#t:from">from</a></code> and <code><a href="/usr/share/doc/ghc-doc/html/libraries/base-4.6.0.1/GHC-Generics.html#t:to">to</a></code> from <code>GHC.Generics</code>,
 and probably won't be explicitly referencing <code><a href="Control-Lens-Representable.html#t:Rep">Rep</a></code> from <code>Control.Lens</code>
 in code that uses generics.
</p><p>This module provides compatibility with older GHC versions by using the
 <a href="http://hackage.haskell.org/package/generic-deriving">generic-deriving</a>
 package.
