I'm working on a project (http://www.cakem.net/) that involves networking. I have to do a lot of decoding of network data into an internal representation, and encoding internal representations into a network format. The decoding part is going to present a problem, a problem that could easily be solved by continuations. I want to right the code so that it will work when there is no guarantee that I'll have an entire message before I start decoding it. This means the parser may have have to stop at any random point in time, and then be restarted again when more data is available. I see no way to do this without continuations, or threads, and I refuse to use threads for something like this. For now, I think I will do one of two things. Either build in the assumption that I will have the entire messages before I start parsing, or organize parsing as a series of steps that can be aborted in the middle and then restarted, and use exceptions to track whether the step was fully completed or not. Sort of a poor man's continuation. Anyway, I'm not a Python developer, just a user. I just wanted to add this to the things you consider when you decide what you intend to do next with Python. Continuations are important, and AFAIK, the stackless mod is the only way to get them. Thanks, -- "It does me no injury for my neighbor to say there are twenty gods or no God.
