#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 agibiansky): @goldfire: The GHC parser (when I cloned master) had 48 shift/reduce conflicts, and this change introduces no new ones (there are still 48). (Actually I just went back to master and recompiled and checked, because I didn't check back when I cloned.) Anyway, this patch introduces no new shift/reduce conflicts. The code {{{ main = - do putStrLn "Hello" }}} causes a parse error with my patch as before, with or without -XArgumentDo enabled. {{{ parse error on input do }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10843#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
