#10892: ApplicativeDo should use *> and <* -------------------------------------+------------------------------------- Reporter: simonmar | Owner: simonmar Type: task | Status: new Priority: normal | Milestone: 8.0.1 Component: Compiler | Version: 7.11 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by ekmett): You often do have to use {{{#!hs _ <- char ')' }}} just to avoid unused result warnings in things like parsers given a parser like {{{#!hs char :: Char -> Parser Char }}} Also, even if you just have do x; y in the ApplicativeDo encoding, nothing currently says that that will invoke (*>) over a manual expansion involving (<*>). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10892#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
