Well, I think simonpj's question was really "why is the same simplification not also being performed when we inline the unfolding?" Indeed this is a good question and will need some investigation.
One explanation could be that `newTyConEtadRhs` is inlined at the callsite of `newTyConInstRhs` because the constructor of `tycon_a9Sq` is known; and after that substitution the logic in comment:9 no longer applies. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/5889#comment:16 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
