This is important, as otherwise this would require a non-neglectable amount of `Control.Monad hiding ((<|>), empty)` imports in user code. The Haddock submodule is updated as well Test Plan: partial local ./validate --fast, let Harbormaster doublecheck it Reviewed By: ekmett, austin Differential Revision: https://phabricator.haskell.org/D248 }}} -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/9586#comment:23> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
