[GHC] #8234: Remove role annotations on type synonyms
#8234: Remove role annotations on type synonyms ------------------------------------+------------------------------------- Reporter: goldfire | Owner: goldfire Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.7 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- Currently, role annotations are allowed on vanilla type synonyms. However, Simon points out that this is very fragile, because a type synonym can be expanded at any time, thus losing a user's intended restriction. Solution: remove these annotations entirely. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8234 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
