#15497: Coercion Quantification -------------------------------------+------------------------------------- Reporter: ningning | Owner: (none) Type: task | Status: new Priority: normal | Milestone: Component: Compiler | Version: Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: | https://ghc.haskell.org/trac/ghc/wiki/DependentHaskell/Phase2 -------------------------------------+------------------------------------- As described in [https://ghc.haskell.org/trac/ghc/wiki/DependentHaskell/Phase2]. We would like to have coercion quantifications back in Haskell Core language. This means in Core we can define types like {{{#!hs \/ (a: k1) . \/ (co : k1 ~ k2) -- an explicit quantification for the coercion -> (a |> co) -- use the name for an explicit cast -> ... }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15497 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
