Actually, the CPRing sums idea is rather orthogonal, so I can probably cook that up first...
Nope, I realised that a useful CPR for sums needs CPR of depth > 1, so I'll pursue the nested CPR idea and all that comes with it first. The wiki page for why splitting off CPR is a good thing is wiki:NestedCPR/SplitOffCPR. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14259#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
