Marc For type-level literals, the man to talk to is Iavor Diatchki. He implemented the current system, and has been working on enhancements. I'm sure he'd welcome help!
There's also quite an active sub-group (on ghc-devs) working on "plug-ins" for the type inference algorithm, aimed at allowing things like better arithmetic reasoning to be done without having to change GHC itself.

As a consequence, I had to | add lots and lots of constraints to make my code work, which | effectively meant the code became unmaintainable because a small | change requlted in lots of errors. | | I know have a bit more time to work on the project and I'd like | to see if it's possible to ``talk'' to somebody in the GHC team | to see if we can improve type-level literal inference for natural | numbers. | | Is there somebody who's ``responsible'' for this area in the GHC | team? If yes, would you mind giving me their contact details? | | Regards, | | | Marc van Dongen _______________________________________________ ghc-devs mailing list [email protected] http://mail.haskell.org/cgi-bin/mailman/listinfo/ghc-devs
