[Twisted-Python] Python 3 progress: Twisted Core, Twisted Names

Hello, Just a heads up about the continuing experiment in porting Twisted to Python 3. The port has reached the point where most of Twisted Core and Twisted Names is now working. The exceptions are: twisted.cred, twisted.protocols.sip, twisted.python.hook. This is validated by running the corresponding test suites. Details about the successful tests are on the project page (*). I have also validated that merging upstream changes (from Twisted's trunk) is relatively painless. The merges produced few conflicts and few regressions (test failures), which were easy to fix. (*) Project page: https://bitbucket.org/pitrou/t3k/, as always. Regards Antoine.
