#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 simonpj): A binding `foo = bar` is already regarded as a function binding in GHC. From `HsBinds`: {{{ = -- | FunBind is used for both functions @f x = e@ -- and variables @f = \x -> e@ -- -- Reason 1: Special case for type inference: see 'TcBinds.tcMonoBinds'. -- -- Reason 2: Instance decls can only have FunBinds, which is convenient. -- If you change this, you'll need to change e.g. rnMethodBinds -- -- But note that the form @f :: a->a = ...@ -- parses as a pattern binding, just like -- @(f :: a -> a) = ... @ }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10756#comment:13 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
