#13490: Ambiguous types with constraints on new variables -------------------------------------+------------------------------------- Reporter: crockeea | Owner: (none) Type: bug | Status: closed Priority: normal | Milestone: Component: Compiler | Version: 8.0.2 Resolution: worksforme | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: GHC rejects | Unknown/Multiple valid program | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by crockeea): Simon, your explanation seems similar to #11948. Are they related? I'm still wondering about this ticket. Why am I getting an ambiguous type error, and since the definition is `undefined`, why does GHC have to do any work at all? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13490#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
