#13649: RebindableSyntax causes type errors when 'fail' is not defined, even if not used. -------------------------------------+------------------------------------- Reporter: AaronFriel | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.1-rc1 Resolution: | Keywords: | RebindableSyntax 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 simonpj): Yes I agree... if the pattern returns true to `isIrrefutableHsPat` we should not look up the fail function. It'd be great if someone could fix this. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13649#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
