This falls in my pile, but it will be a little while until I get to it, so if you (for any value of "you") are inspired, go for it. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12512#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

But that is no longer the case, and so this ad hoc check can be removed entirely. Less code, and easier to understand.
