Tiny Actor Run-Time in Python.
The initial ideas for tartpy are copied from @dalnefre and @tristanls. At the beginning, the goal was to replicate tart.js in Python. Lately, it has diverged slightly, to experiment with the new Python asynchrony model introduced in version 3.4.
tartpy aims to be an actor library with the following features:
- it implements the pure actor model (rather than the Erlang model),
- it can be used in practical situations to express lock-free and concurrent algorithms,
- it abstracts the network transport to allow arbitrary protocols,
- it implements a capability based approach to isolate actors, using membranes (again, the ideas are due to @dalnefre and @tristanls). The semantics of membranes may differ between tartpy and tartjs.

There is also an IPython notebook showing the basic properties of actors.
Create a ring of M actors, sending N messages around the ring:
python3 tartpy/erlang_challenge.py M N
For M = 100000 and N = 10:
