#11715: Constraint vs * -------------------------------------+------------------------------------- Reporter: bgamari | Owner: Type: bug | Status: new Priority: high | Milestone: 8.2.1 Component: Compiler (Type | Version: 8.0.1-rc1 checker) | Resolution: | Keywords: Typeable Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): Yes, it would work to have `TYPE :: Coherency -> RuntimeRep -> Type` instead of the current `TYPE :: RuntimeRep -> Type`. Algebraically, this is just the same as adding more constructors to `RuntimeRep`, as Simon and I have proposed. But I see how this might be preferable. I'm curious for Simon's opinion on this, noting that such a design is independent of the ability to use `Constraint`s to the left of `->` or `Type`s to the left of `=>`. This new design does not solve the problem I outline at the end of comment:47 though. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11715#comment:53 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
