One can build go like things on top of generators, however this doesn't solve your problem, as these generators (pointed to in your link) cannot yield through more than a single function. They have the same semantics as yield in python or C# (or go in Clojure). That is to say every function in the chain must do:
for(x in generator) yield x; In order to pass along the value. This is exactly the same as making every function in your system contain a go, and that go's body containing something like: (go (>! ret-chan (<! (my-func)))) What you are asking for requires something like delimited continuations, and very, very few platforms support this.
