I'm not entirely sure whether I'm hijacking the thread here... I have to admit I've somewhat lost track with all the renames. The discussion has been very interesting (I really like the 'codef' idea, and decorators can provide this without requiring syntax changes) regardless of which thread is active.
I have spent a bit of time writing up the approach that we (Dino, who posted it here originally, myself and with some advice from colleagues who are working on a similar API for C++) came up with and implemented.
I must apologise for the length - I got a little carried away with background information, but I do believe that it is important for us to understand exactly what problem we're trying to solve so that we aren't distracted by "new toys".
The write-up is here: http://stevedower.id.au/blog/async-api-for-python/
I included code, since there have been a few people asking for prototype implementations, so if you want to skip ahead to the code (which is quite heavily annotated) it is at http://stevedower.id.au/blog/async-api-for-python/#thecode or http://stevedower.id.au/downloads/PythonAsync.zip (I based my example on Greg's socket spam, so thanks for that!)
And no, I'm not collecting any ad revenue from the page, so feel free to visit as often as you like and use up my bandwidth.
Let the tearing apart of my approach commence! :)
