Right, like now. CPython has the necessary stackless hooks, nuts
and bolts, but nothing else, and no speed impact.

Then is just happens to be *possible* to write such an extension,
and it will be written, but this is no language feature.

This was my sentence, in the first place, but when reviewing
the message, I could not resist to plug that in again <1.5 wink>

As discussed in a private thread with Just, some continuation
features can only be made "nice" if they are supported by
some language extension. I want to use Python in CS classes
to teach them continuations, therefore I need a backdoor :-)
