#15645: TypeChecking of Monad patterns incorrect with RebindableSyntax and OverloadedStrings -------------------------------------+------------------------------------- Reporter: NeilMitchell | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Compiler | Version: 8.4.3 Resolution: | 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 NeilMitchell): Indeed, you can't use the name fail, which is unfortunate. The mysterious messages about things already happens - I get an error about `[Char]` vs `Text` - so the `IsString` thing is just the same consequence. I'd view this as a bug fix (overloaded strings should imply even generated strings are overloaded, if they are passed to user-controlled functions), but happy to go through GHC proposal process. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15645#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
