If the code above reflects something you want to do, I could just add it to our regression tests. It seems to be a relatively sophisticated use of `QuantifiedConstraints`! I'm not following the details but I'm sure that you and Iceland Jack will tell us if any further infelicities show up. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14961#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
