I did re-read the post and it just seems like perl 6 has reassured him that python is dying but I have to disagree, maybe jython is dead for what he wants but python is not dead and from the looks of it jython is not dead.
Python is not dead. Python is hurting from a bad design decision that doesn't let multiple interpreter implementations share components that they could have. This makes it impossible for minimally maintained branches (like Jython) to keep up with the language, and so hard for better-maintained branches (like IronPython or pypy) that it necessitates a moratorium on the syntax as a whole.
I still think python's focus is in a slower world and as a python user I am okay with that.
As many others have said, changing syntax is really one of the most trivial parts for alternative implementations to keep up with when moving to new versions. That "hurt" hasn't been fixed because it doesn't really hurt very much...
