#10828: TH could do a better job of representing GADTs -------------------------------------+------------------------------------- Reporter: spinda | Owner: jstolarek Type: feature request | Status: new Priority: normal | Milestone: 8.0.1 Component: Template Haskell | Version: 7.10.2 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 jstolarek): My proposal would be to add the following constructor to `Con` data type: {{{#!hs | GadtC Name [StrictType] [Type] }}} where the last field stores list of constructor indices. Once we have this new constructor I would modify `DsMera` and `Convert` accordingly. Most importantly, GADT declarations would be now translated to use this new constructor instead of encoding that uses `ForallC` and `NormalC`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10828#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
