#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 AaronFriel): Interesting, I thought that the lack of the constraint meant that GHC here was not following that spec. How does the `fail` get removed such that it doesn't entail a constraint? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13649#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
