#10023: Relax Monad constraint in traceM and traceShowM to Applicative -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: libraries/base | Version: 7.10.1-rc1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Other | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by ekmett): We've adopted the practice of generalizing the existing fooM Combinators in base where possible as part of 7.10 but not giving a new set of fooA names to avoid namespace pollution, needless constraints and a complex deprecation cycle. It seemed the lesser of evils was to generalize the M suffix than ask literally everyone to retool. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10023#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
