#1311: newtypes of unboxed types disallowed - documentation bug and/or feature request -------------------------------------+------------------------------------- Reporter: Isaac Dupree | Owner: osa1 Type: feature request | Status: new Priority: low | Milestone: ⊥ Component: Compiler | Version: 7.7 Resolution: | 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: | -------------------------------------+------------------------------------- Comment (by goldfire): I don't see a problem thus far. But as I said in my previous comment, you may need to unify that result kind with `*` in the datatype case somewhere. Perhaps a `_ <- unifyType blah blah (typeKind res_ty) liftedTypeKind` would do the trick, but perhaps something more elaborate is necessary. I do think you're pushing in the right direction, though. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/1311#comment:14 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
