Err... thank you once again for being redundant, reiterating what is already pretty much dead clear to everyone and saying nothing new in general. * Yes, Aahz DID answer my question regarding reuse of Python 2.x implementation in Py3K * Yes, Guido DID ask for a prototype implementation for anyone who would lobby for a new async mechanism * Yes, generators are quite easy to write, use, modify and read (once you get the concept), except I don't see how you can easily use them to implement non-blocking I/O in their current state (I believe I've already mentioned that twice)... Let's see... anything else I've missed? Oh yeah... * _Some_ parts of Py3K will be backwards incompatible Could anyone be possibly more condescending as to have to repeat that... ??? You must think other people pay even less attention to things than you do. > The question really is whether or not Io or stackless style > continuations are better than what currently exists. Actually... it's whether or not a futures-inspired abstraction would make for a more pythonic asynchronous mechanism compared to an enhanced generator as described in PEP 342. Nothing to do with Io or Stackless per se. I guess you weren't really paying attention that time too.
