Massive Concurreny with PyPy Stackless

(via)

PyPy had its
1.0 release
recently.

Now, This looks *really* interesting:

PyPy Stackless

PyPy can expose to its user language features similar to the ones present
in Stackless Python: no recursion depth limit, and the ability to write code in a
massively concurrent style. It actually exposes three different paradigms to choose
from:

  • Tasklets and Channels
  • Greenlets
  • Plain Coroutines
