**Packages**- package

This library makes it easy to implement monads with tricky control flow.
This is useful for: writing web applications in a sequential style, programming games with a uniform interface for human and AI players and easy replay capababilities, implementing fast parser monads, designing monadic DSLs, etc.
See the project homepage http://haskell.org/haskellwiki/Operational for a more detailed introduction and features.

Version 0.2.2.1

A reimplementation of the operational package (http://hackage.haskell.org/package/operational) using free monads (from http://hackage.haskell.org/package/free). This implements ideas discussed here:
* http://stackoverflow.com/questions/14263363/is-operational-really-isomorphic-to-a-free-monad
* http://www.reddit.com/r/haskell/comments/17a33g/free_functors_the_reason_free_and_operational_are/
To understand the basic concepts you can do no better than read Heinrich Apfelmus' operational tutorial:
* http://apfelmus.nfshost.com/articles/operational-monad.html
In addition to that, this package supplies operational-style modules for Applicative, Alternative and MonadPlus. Applicative and Alternative programs easily admit of static analysis. See these references for discussion and examples:

See Control.Applicative.Operational for the bulk of the documentation. Control.Alternative.Operational also has some significant examples.
