Comment 1 for bug 1038822

This is really two entirely separate bugs:
1. Port IVLE to Python 3,
2. Allow user code (console, worksheets, and serve URLs) to be Python 3 code.
(2 may be split into three sub-tasks as well.)

I would suggest that 2 is quite desirable; 1 is not worth the effort by a long shot. Back in the day, we talked about the possibility of plugging in alternative interpreters to IVLE (such as Ruby), and Python 3 would be just another of those interpreters. IVLE is certainly capable of running Python 3 code without itself being written in Python 3.
