I think Pulsar supports this model: http://docs.paralleluniverse.co/pulsar/#error-handling http://docs.paralleluniverse.co/pulsar/#error-handling. Incidentally, in the javascript port of core.async, we are also trying to come up with a good error handling story [1]. One approach we are considering is (sort of) adapting the Erlang model, by treating goroutines' return channels as their identities. I'm researching error handling in CSP literature and prior implementations as well. [1]: https://github.com/ubolonton/js-csp/issues/14 https://github.com/ubolonton/js-csp/issues/14
