@hackage CC-delcont0.1

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 (http://www.cs.indiana.edu/~sabry/papers/monadicDC.pdf). 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 (http://okmij.org/ftp/papers/DDBinding.pdf), adapted from the original haskell code, (http://okmij.org/ftp/packages/DBplusDC.tar.gz).
