 Given a haskell file;

 {{{#!hs
 {-# LANGUAGE DuplicateRecordFields #-}
 -- t.hs

 data A = A { name :: String }
 data B = B { name :: String }
 }}}

 and in GHCi;

 {{{
 ghci t.hs
 GHCi, version 8.1.20151231: http://www.haskell.org/ghc/  :? for help
 [1 of 1] Compiling Main             ( tnum.hs, interpreted )
 Ok, modules loaded: Main.
 *Main> <TAB> <TAB>
 ...
 $sel:name:A
 $sel:name:B
 ...

 }}}

 The records show up as `$sel:function:Type`, a function which you cannot
 refer to by name.

 Even if you enable `OverloadedLabels`, the `#labels` don't show up in the
 auto completion.
