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. That would give clear and intuitive code for things like simulations... Thanks, Andreas. ------------------------------------------------------------------------ Andreas Gruenbacher gruenbacher@geoinfo.tuwien.ac.at Research Assistant Phone +43(1)58801-12723 Institute for Geoinformation Fax +43(1)58801-12799 Technical University of Vienna Cell phone +43(664)4064789
