#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 goldfire): I'm with @rwbarton. The fact that `B` is `COMPLETE` in comment:5 does not make the first match redundant or inaccessible. His suggestion to consider `pattern B <- _` (which is indeed a complete pattern) is instructive. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13021#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
