#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): How would we write the body for, say, `with :: c -> (c => r) -> r`? What about `whichOne :: c -> c -> (c => r) -> r` (which takes two elements of type `c`)? I'm worried that the disadvantages of comment:11 are a bit painful. Perhaps no worse than where we are now, though. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11715#comment:18 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
