#10457: Revise/remove custom mapM implementation for lists -------------------------------------+------------------------------------- Reporter: dolio | Owner: Type: task | Status: new Priority: normal | Milestone: 7.10.2 Component: libraries/base | Version: 7.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: Phab:D924 -------------------------------------+------------------------------------- Comment (by simonmar): Hmmm, so this is only a transparent change for Monads that have `<*> = ap`. Arguably since it is possible to write legal (though unconventional) Haskell that behaves differently, and it's not a bug fix, it should not go into 7.10.2. (arguing against my own best interests, because it being in 7.10.2 would be helpful for me, but I've been working around it for a while so I can continue to do so) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10457#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
