#10976: Applicative Comprehensions -------------------------------------+------------------------------------- Reporter: davidar | Owner: Type: feature | Status: new request | Priority: normal | Milestone: 8.0.1 Component: Compiler | Version: Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: 8914 | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- As discussed on `ghc-devs`, when both the `MonadComprehensions` and `ApplicativeDo` language extensions are enabled, it should be possible to use comprehension-notation (in addition to do-notation) for `Applicative`s. This would allow, for example, an expression like {{{#!hs (\x y -> x + 2*y) <$> ZipList [1..10] <*> ZipList [10,20..100] }}} to also be written as {{{#!hs [ x + 2*y | x <- ZipList [1..10], y <- ZipList [10,20..100] ] }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10976 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
