See #10009. As a side note: I don't think it is correct to call this a bijection. Bijection means that we have injectivity (which is true) and surjectivity (which is not true). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10634#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
