comment:3 talks about parking Coercible constraints in the insolubles
Actually the `Coercible b (f b)` constraint is parked in the inert dicts. But the `b ~R# f b` constraint is parked in insolubles. It probably shouldn't be. But in fact I want to kill off the insolubles altogether, and combine then with tie irreducibles. I don't think the distinction pays its way. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14323#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
