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,
