#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 alexbiehl): I have put together a proof of concept [https://github.com/alexbiehl/ghc/commit/57a1a3506c90f2b8f75014ca71ca6b673060... here]. It supports newtypes over unlifted data *and* unlifted data types (with unpacking). This is done without much knowledge about what is a right or wrong thing to do. But I would be happy if we could discuss it and maybe make it a patch we all agree with. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/1311#comment:18 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
