#15927: Weird interaction between fundeps and overlappable instances -------------------------------------+------------------------------------- Reporter: Darwin226 | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.3 Component: Compiler | Version: 8.6.2 Resolution: | Keywords: | FunctionalDependencies Operating System: Unknown/Multiple | Architecture: Type of failure: GHC accepts | Unknown/Multiple invalid program | Test Case: Blocked By: | Blocking: Related Tickets: 10675, 15632 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by Darwin226): Well, since the mtl default is to no only disallow multiple states of the same type, but multiple states of ANY type, I wouldn't really call this non-scaleable. It's strictly more flexible than mtl. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15927#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
