#9754: Fix Applicative instances in the wake of AMP -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: dfeuer Type: task | Status: new Priority: normal | Milestone: 7.10.1 Component: Core Libraries | Version: 7.8.3 Keywords: AMP | Operating System: Architecture: Unknown/Multiple | Unknown/Multiple Difficulty: Unknown | Type of failure: Other Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- I haven't tracked down all the problems yet, but several experiments leading to validation failures strongly suggest that some `Applicative` instances in the GHC tree fail to interact properly with their associated `Monad` instances. That is, `ap ≠ (<*>)` and/or `(>>) ≠ (*>)`. We should be able to fix these up by fleshing out the appropriate instance declarations. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9754 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
