-- Stability   :  provisional
-- Portability :  Rank2Types
--
-- Usage:
--
-- You can derive lenses automatically for many data types:
--
-- @
-- import Control.Lens
-- data Foo a = Foo { _fooArgs :: ['String'], _fooValue :: a }
-- 'makeLenses' ''Foo
-- @
--
-- This defines the following lenses:
--
-- @
-- fooArgs :: 'Simple' 'Lens' (Foo a) ['String']
-- fooValue :: 'Lens' (Foo a) (Foo b) a b
-- @
--
-- You can then access the value with ('^.') and set the value of the field
-- with ('.~') and can use almost any other combinator that is re-exported
-- here on those fields.
--
-- The combinators here have unusually specific type signatures, so for
-- particularly tricky ones, the simpler type signatures you might want to
-- pretend the combinators have are specified as well.
--
