synopsis:            Operational Applicative, Alternative, Monad and MonadPlus, built with free types.

description:         
    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.
