And if it does fail, try to import <br>greenlets. Also keep the old greenlet code. This is very much the way the previous stackless.py<br>worked.<br><br>>As I said already, I implemented the code so far but I don't really<br>>have deep interest myself in this feature. If someone wants seriously<br>>to start working on it, I can give a few hints.<br><br>I would be happy to work with other folks that are interested in the stackless.py module. I have a <br>patchy knowledge of PyPy but a decent knowledge of stackless.py and stackless. Let me study continuations and the existing
stackless.py module. In
this fashion, I can make every hint I ask count.<br><br>> Otherwise, I'm sorry but I'm not going to take an active part in design discussions about<br>>how stackless features could be improved.<br><br>As discussed on IRC, I think an approach that would work is fork stackless.py in two. One branch would be conventional. That that, it would track C basedStackless but incorporate stuff like continuelets and bug fixes and more conservative features.<br><br>The other branch would be experimental. Wilder stuff would be done there.<br><br>Cheers,<br>Andrew<br><br><br><br><br><br></div></div></div></div><div><meta http-equiv="x-dns-prefetch-control" content="on"></div></div></body></html>
