It is not ERTS / BEAM. Acton has its own run time system. Acton code is compiled to C functions, so the execution of functions look quite different between BEAM and Acton RTS. Acton has a Pythonic syntax but is NOT Python, so there is no GIL - quite the contrary, the Acton RTS runs actors concurrently.

I'm afraid that Acton in itself won't teach "how to architect systems on actors". I do wholeheartedly relate to the challenge. It's not easy to switch and think "natively" in a new paradigms. Go try it out, do Advent of Code in Acton and see how it feels ;)
