#10756: Allow users to indicate inaccessible patterns -------------------------------------+------------------------------------- Reporter: edsko | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by goldfire): Thanks for writing that up. I like it. My only complaint is the choice of the word `impossible`, which becomes a full-fledged keyword under this proposal. If someone wants to use `ImpossibleCases` and they import a symbol named `impossible`, can they use it? I suppose using it qualified wouldn't conflict. And no exported symbol named `impossible` comes up at http://www.stackage.org/lts-2.22/hoogle?q=impossible I don't have a better suggestion among the set of keywords/keyoperators. So I vote +1 for the proposal exactly as is. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10756#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
