Lazy evaluation *is* coroutines, in a way. Or you may be interested in Concurrent Haskell See section 4 of "Tackling the awkward squad" http://research.microsoft.com/~simonpj/papers/marktoberdorf.htm Simon | -----Original Message----- | From: Andreas Gruenbacher [mailto:gruenbacher@geoinfo.tuwien.ac.at] | Sent: 19 March 2001 17:00 | To: haskell-cafe@haskell.org | Subject: Coroutines | | | Hello, | | has anybody thought about how to implement Simula style coroutines in | Haskell? What I have in mind is several "procedures" that | communicate via | message passing in a co-operative way.
