How so?  It would still be nice to have some syntax on the
language to support generators.  If the implementation supports
continuations then implementing PEP 255 will be easy.

I don't know what you mean by simulation loops.

Make that "much easier".  Stackless is wizard code.  Christian
did an amazing piece of work there.  Hopefully those ideas can
be integrated into mainstream Python.  Its still going to take a
lot more work though.  So far no one has stepped forward to do
it.
