In my opinion, a move to Python 3 would be great, but is being hampered by two things, at least based on what is in the 'py3' branch:

* The "move" to Python 3 isn't really a move; the code is being updated in such a way as to preserve Python 2 compatibility.

* At the same time as moving to Python 3, the UI technology is being switched from Gtk to wxPython.

If it was just a straight *move* to Python 3, dropping Python 2 and allowing developers to take full advantage of Python 3 features, I, and I suspect others, would be more interested in helping out, since I don't honestly see much point in keeping Python 2 compatibility any more. As you say, it's been EOL for a while.

Also, I feel that switching the UI technology should be a separate effort from updating the language version, unless there's some compelling reason that the two cannot be done sequentially. I'd say get to Python 3 first, and then maybe think about switching UI technologies.

My 2 cents.

Martin.
