I believe that this is accepted and works as I had intended on 7.8.3 (with the correct definition as well) after talking to some people on IRC, but I haven't personally tested it
It only works with `undefined` in 7.8.3. The proper implementation fails. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10651#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
