#10843: Allow do blocks without dollar signs as arguments -------------------------------------+------------------------------------- Reporter: agibiansky | Owner: agibiansky Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.2 (Parser) | 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 Rufflewind):
I don't see a common usecase for case, if, and let
I've certainly written code like this: {{{#!hs foo x = pure $ case x of Just _ -> True Nothing -> False }}} Personally I never understood why `$` was required to begin with. There's no sensible way to interpret `runST do …` except as `runST (do …)`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10843#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
