I haven't given the WAI specification much attention since I first wrote it. Mostly because I'm caught up in thinking about enumerators and their role in e.g. an HTTP server implementation.
Do you have any result?
Yes and no. Hyena used to mix imperative and iteratee style code internally, making the code hard to work with and certain HTTP features hard to implement correctly. It now uses iteratees everywhere. This makes for a more robust and easily extensible implementation. To give you an example I had a hard time implementing pipelining using the old implementation. That should be much easier now. I still don't know iteratees place in the grand scheme of things. I don't even know what's a general, well performing and easily graspable definition would look like! In summary: I have *a* definition of iteratees that works. I just don't know if there's a better one. Cheers, Johan
