#12702: Don't warn about redundant constraints for necessary -------------------------------------+------------------------------------- Reporter: crockeea | Owner: Type: bug | Status: closed Priority: normal | Milestone: 8.0.2 Component: Compiler | Version: 8.0.1 Resolution: fixed | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by RyanGlScott): * status: new => closed * resolution: => fixed * milestone: => 8.0.2 Comment: I can't reproduce the warning on GHC 8.0.2. Sadly, this test case requires lots of `singletons` machinery, which is darn-near impossible to boil down to a simple test case. I'm going to just close this as being fixed in 8.0.2. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12702#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
