#10755: Add `MonadPlus IO` and `Alternative IO` instances -------------------------------------+------------------------------------- Reporter: hvr | Owner: Type: task | Status: patch Priority: normal | Milestone: 7.12.1 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 Revisions: Phab:D1148 -------------------------------------+------------------------------------- Comment (by RyanGlScott): If removing them from `transformers` causes too much heartburn, I'd be fine with asking Ross to put them back. My rationale when making that pull request was that putting orphan `IO` instances in a library about monad transformers didn't make much sense, and probably belong somewhere like `base-orphans` instead. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10755#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
