#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 mpickering): It is easy to trigger cases like this with `COMPLETE` signatures as they are currently designed. For example, {{{ data T = A | B | C {-# COMPLETE B #-} foo :: T -> () foo A = () foo B = () }}} Then the first match is reported as having an inaccessible RHS. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13021#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
