PEP 3156 (Asynchronous IO Support Rebooted: the "asyncio" Module) was accepted 18 months ago, and since then we've aggressively test-driven it in the 3.4 stdlib. I think that in some cases we've changed or added APIs or changed semantics, and I would like to update the PEP to match reality (so that people reading the PEP as a specification aren't going to be confused). If you're good at reading and editing technical documentation I'd love for you to help me with this! (Another form of help I could use might be to check the docs on docs.python.org against the PEP and the implementation.) -- --Guido van Rossum (python.org/~guido)
