#8503: New GeneralizedNewtypeDeriving check still isn't permissive enough -------------------------------------+------------------------------------ Reporter: goldfire | Owner: goldfire Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.7 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: #8541 -------------------------------------+------------------------------------ Comment (by simonpj): There are plenty of other ways to construct exponentially-sized types (even in H-M),so I don't think we should worry here. Remember too that type functions mean that the entire notion of a "recursive newtype" is suspect. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8503#comment:28 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
