#1965: Allow unconstrained existential contexts in newtypes -------------------------------------+------------------------------------- Reporter: guest | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 6.8.1 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 simonpj): Oh sorry, my fault.

Back to comment:9 then, I think. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/1965#comment:26 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
