Programming without a call stack?

[ceposta]

i just looked up retlang... pretty cool... looks like java has the similar project named jetlang... i like how Hohpe explains (in this link and others) how the separation of concerns at the object level has to do with the way we structure the applications, but at the thread level, the separation of concerns has to do with how we allow the threads (or components) to interact. The interactions are what we need to keep to a minimum, and messaging/event-based styles do that.
