Thanks! Can you enumerate what the "unarisation issues" are, precisely?
This is mostly from memory, so may not be as precise as I would like, however: * StgLint does not currently account for the fact that the types and number of arguments to `StgRhsCon`, `StgConApp` and `StgApp` change after unarisation. * StgLint does try to account for the unarisation changes in case scrutinees and Alts, but it's not quite right. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14536#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
