#13021: Inaccessible RHS warning is confusing for users -------------------------------------+------------------------------------- Reporter: mpickering | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: | PatternMatchWarnings Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by rwbarton): I don't understand what is going on in this example. Suppose `B` was a pattern synonym and we couldn't see its definition. Then the `COMPLETE` pragma could be semantically correct. But if we match `A` before `B` then the match isn't redundant, the behavior of the function could be different in the `A` case. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13021#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
