A monad transformers for multi-prompt delimited control

Latest on Hackage:0.1.0.0

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

This library implements the superset of the interface described in * A Monadic Framework for Delimited Continuations, R. Kent Dybvig, Simon Peyton Jones, and Amr Sabry JFP, v17, N6, pp. 687--730, 2007. http://www.cs.indiana.edu/cgi-bin/techreports/TRNNN.cgi?trnum=TR615

This library is the most direct implementation of the bubble-up reduction semantics of multi-prompt delimited control. The library stands out in not being based on the continuation monad. Rather, the monad of Control.Monad.CC.CCExc is an extension of the Error monad: a monad for restartable exceptions. The library offers not one monad transformer but a family (CC p) parameterized by the prompt flavor p . The library defines several prompt flavors; the users are welcome to define their own.

See the original article at http://okmij.org/ftp/continuations/implementations.html#CC-monads for more information.

This package split multi-prompt delimited control from http://hackage.haskell.org/package/liboleg for usability.
