#12784: Typechecker regression in GHC 8.0.2 involving DefaultSignatures -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: Type: bug | Status: patch Priority: highest | Milestone: 8.0.2 Component: Compiler | Version: 8.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: GHC rejects | Unknown/Multiple valid program | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D2682 Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): The change in behavior is surely a bug fix here. Changes in user-facing behavior between minor versions due to bug fixing are OK. And I agree with Ryan's phrasing in the Phab Diff. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12784#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
