As to comment:22, it sounds like you wish to distinguish between `INCOHERENTABLE` and `INCOHERENTING`. (I don't want to use those names, just draw the parallel to the `OVERLAP` pragmas.) Is this a reasonable interpretation of what you're saying?
Yes, but I ''really'' don't want to actually have that complexity. Obvious alternatives: * Current behaviour: INCOHERENT means INCOHERNTING * Behaviour proposed in comment:22: INCOHERENT means INCOHERENTABLE * Another alternative: INCOHERENT means both INCOHERENTING and INCOHERENTABLE -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9242#comment:24 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
