[Haskell-cafe] Coroutines

[Mario Blazevic]

	Another implementation of coroutines is in the Streaming Component 
Combinators on Hackage 
(http://hackage.haskell.org/cgi-bin/hackage-scripts/package/scc). In 
this version, a coroutine is a monad transformer that can be laid over 
any monad, including Id and IO. Furthermore, you can have an arbitrary 
number of inputs/output channels but they are restricted to 
communicating a single value type.
