Maybe this is possible, but that's not a reason to do it. I have spent a little too much of my lifetime with taming continuations. And since Python has all the control flow it needs, it does not make sense to add continuations, which impose extra complications for no gain. I think to stick with coroutines as the building block, unless there is a real need for continuations. cheers - chris -- Christian Tismer :^) <mailto:[EMAIL PROTECTED]> tismerysoft GmbH : Have a break!
