#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 gkaracha): Even though I understand that the message can be confusing, I disagree with calling it in any way "redundant". Pattern matching is side-effectful in a lazy language and in fact we often use it just to force evaluation, so I would not consider it a minor thing. Before GHC 8, both redundant and with-inaccessible-rhs clauses where called "overlapping" which may be more appropriate. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13021#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
