#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 YitzGale): Replying to [comment:11 goldfire]: I agree. I anyway wasn't thinking of turning everything into a pattern binding. Other than type aliases and record syntax, the LHS of = is either a function binding or a pattern binding, both of which include a pattern expression. In both cases `impossible` following the pattern expression makes sense, provided that the pattern expression is non-empty. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10756#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
