#5927: A type-level "implies" constraint on Constraints ----------------------------------------+----------------------------------- Reporter: illissius | Owner: Type: feature request | Status: new Priority: normal | Milestone: 7.6.2 Component: Compiler (Type checker) | Version: 7.4.1 Keywords: | Os: Unknown/Multiple Architecture: Unknown/Multiple | Failure: None/Unknown Difficulty: Unknown | Testcase: Blockedby: | Blocking: Related: | ----------------------------------------+----------------------------------- Comment(by illissius): I know about it (referenced it actually in an earlier comment), thanks! I don't think I have an actual practical problem to be worked around. I was just experimenting, exploring, and testing the limits of what's possible. As usual I hit them. -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/5927#comment:10> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

It allows you to manually enter and use implication relationships. This doesn't solve the fundamental problem here, but it may help with a workaround. -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/5927#comment:9> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

The best I can suggest is to clone the project and look back for a commit around the same date as this bug report. Or, just close this bug and see if someone else runs into it. -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/7557#comment:3> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
