%description
This is an extensible effects library for Haskell taking inspiration from the
Eff language <http://www.eff-lang.org/>.

See these papers for the ideas and theory behind the library:

- O. Kammar et al: Handlers in Action!
<http://homepages.inf.ed.ac.uk/slindley/papers/handlers.pdf> - A.
Bauer, M. Pretnar: Programming with Algebraic Effects and Handlers
<http://arxiv.org/abs/1203.1539> - O Kiselyov, A Sabry, C Swords: Extensible
Effects <http://dl.acm.org/citation.cfm?id=2503791>

Implementation wise it's most close to 'extensible-effects'
<http://hackage.haskell.org/package/extensible-effects> (also see the
Extensible Effects paper) but it implements deep handlers instead of shallow.

' import Control.Effects.Cont.Eff import Control.Effects.Cont.Reader import
Control.Effects.Cont.Exception

program = do &#32;&#32;v <- ask &#32;&#32;if v < 15 &#32;&#32;then throw $ show
v &#32;&#32;else return (v+1)

run n = runPure . handle exceptionHandler . handle (readerHandler n)

res :: Integer -> Either String Integer res n = run n program '.
