AsyncFlows: Structured Asynchronous Programming

I've just made a public release of AsyncFlows framework 0.1.0 that offers DSL for structured and object-oriented asynchronous programming.

Some differences from competing solutions:

  • The framework is implemented in pure Java, there are no compiler extensions used. The same ideas are implementable in any garbage-collected language with reasonable lambdas and where it is possible to implement event queues and promises. The better are lambdas, the better code looks. Kotlin and Groovy versions looks much better than Java version.
  • There is no event matching and alomst no explict working with events. Explicit sending and event receiving are considered in the framework as "go to" of asynchronous programming and they should be avoided for the same reasons. Actually framework just uses one type of events: executable action.
  • The focus is intra-process coordination. The inter-process communication is considered as subject for libraries, there is no communication model enforced.
  • The focus during development are asynchronous operations and their combination using operators. Just like when developing in Java or C the focus are composing blocks, statements, loops, etc. The DSL is inspired by Occam and E language and it provide a set of orthogonal operators (all, seq, any, seq while, etc.).

I would like feedback on DSL struture and on the thesis that explicit event sending to queues or channels is "go to" of asynchronous programming and that it should be avoided if we try to get understandable code.
