Note that while Stackless Python makes coroutines and similar things easy, it offers more: You can serialize all the runtime elements like the stack trace and that data is platform independent. That gives you very nice possibilities, like moving some thread over to a different machine. Or serialize to disk and resume at some later time - maybe after a reboot or after some edit of the code. That is also great for debugging and inspection. It makes Python much more dynamic - and somewhat more similar to Smalltalk.
