http://hackage.haskell.org/cgi-bin/hackage-scripts/package/CC-delcont-0.1 An implementation of multi-prompt delimited continuations based on the paper, A Monadic Framework for Delimited Continuations, by R. Kent Dybvig, Simon Peyton Jones and Amr Sabry It also includes a corresponding implementation of dynamically scoped variables, as implemented in the paper, Delimited Dynamic Binding, by Oleg Kiselyov, Chung-chieh Shan and Amr Sabry sitting on hackage, thanks to the work of Dan Doel, who jumped in to fill a gap in the libraries. -- Don _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
