#14273: Typed holes' "valid substitutions" suggestions are oblivious to type class constraints -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler (Type | Version: 8.3 checker) | Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Poor/confusing | Unknown/Multiple error message | Test Case: Blocked By: | Blocking: Related Tickets: #9091 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by Tritlo): I'll have a look at the incorrect suggestions! About the missing constraint: if you add the -fshow-hole-constraints flag, you'll get a "Constraints include" part in the hole's type error message. Maybe it should be on by default? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14273#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
