#10755: Add `MonadPlus IO` and `Alternative IO` instances -------------------------------------+------------------------------------- Reporter: hvr | Owner: Type: task | Status: patch Priority: normal | Milestone: 8.0.1 Component: Core Libraries | Version: Resolution: | Keywords: report-impact Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D1148 -------------------------------------+------------------------------------- Comment (by RyanGlScott): The orphan `MonadPlus IO` and `Alternative IO` instances are back in the upstream version of `transformers` (guarded by `#ifdef`s so that they won't be defined in GHC 7.11 and later), so that should no longer be an issue as far as this ticket is concerned. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10755#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
