#9840: Permit empty closed type families -------------------------------------+------------------------------------- Reporter: adamgundry | Owner: Type: feature request | Status: merge Priority: normal | Milestone: Component: Compiler (Type | Version: 7.8.3 checker) | Keywords: Resolution: | Architecture: Operating System: Unknown/Multiple | Unknown/Multiple Type of failure: None/Unknown | Test Case: indexed- Blocked By: | types/should_compile/T9840 Related Tickets: #8028 | Blocking: | Differential Revisions: Phab:D841 -------------------------------------+------------------------------------- Comment (by thoughtpolice): So, this one visibly changes the API and requires a Haddock update, so I'm pretty inclined to leave it as is and not merge. Adam, is this one critical, or can it be worked around/backported reasonably? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9840#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
