#14917: Allow levity polymorhism in binding position -------------------------------------+------------------------------------- Reporter: andrewthad | Owner: (none) Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.2 Resolution: | Keywords: | LevityPolymorphism 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): You know, this is all very much like unboxed tuples. Unboxed tuples are themselves levity polymorphic, must be levity monomorphic at use sites, and have a compulsory unfolding. So perhaps much of the plumbing is installed already. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14917#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
