Re: Stackless Python

Hi Tom,

I'd be interested working with your code when it becomes available. 
I'm doing a project in Python, and at the moment am using a very
simple implementation of channels which I threw together.  My
implementation is quick and dirty, or rather achingly slow and dirty
(depending on whether we consider development time or commstime), and
I look forward to evaluating yours.
