#15621: Error message involving type families points to wrong location -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Compiler (Type | Version: 8.4.3 checker) | Resolution: | Keywords: TypeFamilies Operating System: Unknown/Multiple | Architecture: Type of failure: Poor/confusing | Unknown/Multiple error message | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj):
The solution to #14185 improves the status quo, but only by a lucky coincidence (that the problems in both tickets stem from two different functions)
NO, as I say in comment:7, each type signature makes a new implication constraint, so that'll keep their constraints separate. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15621#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
