#12618: Add saturated constructor applications to Core -------------------------------------+------------------------------------- Reporter: simonpj | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 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 carter): I'd like to chime in and agree that it would be a good design to reflect saturated function application and related info into a corresponding multi arg saturated app application form. I've some woke in progress type theory developments critically use having a built in motion of simultaneous arguments and results (a la types are calling conventions or sequent core), where the logical strength of what can be described needs a built in motion of simultaneous arguments. I presume / assume this multi arg app form is essentially a function application against an unboxed tuple? Right? One thing I'd like to point out is that a knock on effect of this change you may want to consider is having Unboxed tuples in arg and return positions act like pi and sigma telescopes respectively. If what I'm sketching out needs more clarity, I'm happy to do a clearer exposition on the wiki or the like If the meat of the ideas discussed / articulated are consistent with / facilitated by the details I'm hopefully articulating clearly, this would be a set of changes I would strongly support. In. Fact I could probably get support for putting work time into helping out on this change if need be. Partly because then certain ideas I would like to experimentally add to ghc would then be much much easier to add :) (The simultaneous arguments stuff makes embedding / supporting linear logical stuff in a clean way much nicer than previous efforts p) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12618#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
