Also, in case someone looks here: The branch cpr-sum-types is considered dead; Its last commit ([9b0d70e/ghc]) is from October 2011, while CPR for sum types has hit master in January 2013 ([d3b8991/ghc]). (Maybe we should rename dead branches to dead/...?) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/5075#comment:17 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
