-- | Generic deriving of <a>Read</a> / <a>Show</a> with no record labels.
--   
--   Often one wants to create a <tt>newtype</tt> which has a convenient
--   field accessor like <tt>unUserId</tt> below, but that unfortunately
--   makes the <a>Show</a> instance which is derived overly verbose.
--   
--   For example:
--   
--   <pre>
--   newtype UserId = UserId { unUserId :: String }
--     deriving (Read, Show)
--   </pre>
--   
--   <pre>
--   &gt;&gt;&gt; show (UserId "simon")
--   UserId {unUserId = "simon"}
--   
--   &gt;&gt;&gt; read "UserId {unUserId = \"simon\"}" :: UserId
--   UserId {unUserId = "simon"}
--   </pre>
--   
--   With <tt>DerivingVia</tt> <a>Quiet</a> you can have a <a>Show</a>
--   instance which doesn't print the field labels. It will render as if
--   the <tt>unUserId</tt> accessor wasn't present at all.
--   
--   <pre>
--   newtype UserId = UserId { unUserId :: String }
--     deriving (Generic)
--     deriving (Read, Show) via (Quiet UserId)
--   </pre>
--   
--   <pre>
--   &gt;&gt;&gt; show (UserId "simon")
--   UserId "simon"
--   
--   &gt;&gt;&gt; read "UserId \"simon\"" :: UserId
--   UserId "simon"
--   </pre>
--   
--   If you want to derive <a>Read</a> / <a>Show</a> without using
--   <tt>DerivingVia</tt> then you can use <a>qreadPrec</a> and
--   <a>qshowsPrec</a> directly.
--   
--   <pre>
--   instance Read UserId where readPrec = qreadPrec
--   instance Show UserId where showsPrec = qshowsPrec
--   </pre>
