I thought constrained types were Haskell 98, but now I'm in doubt... > But at first sight, implementing support for parametric types with class > constraints is not too hard.

An arguable solution: http://portal.acm.org/citation.cfm?id=1159868 The reason I mention this is because Scrap your Boilerplate supports them whereas GH does not, and I'm not aware this has been taken into account when comparing these two approaches in the work cited by Bulat on this thread. _______________________________________________ Haskell-Cafe mailing list [email protected] http://www.haskell.org/mailman/listinfo/haskell-cafe
