Hi Raffaello,
Python 2.x and 3.x can co-exist without any problem, there shouldn't be anything special to do besides making sure python 2.7 is installed.
No environment variables should be necessary. We use `python2.7` as mx's python interpreter and fallback to `python2` if that doesn't exist. If `python2` also doesn't exist only then do we use the ambiguous `python`.
When a distribution "transitions" to python 3.x, it just means that the `python` symlink goes to Python 3.x instead of 2.x.
We have already used mx in distributions where Python 3 is the default without any problem.
I don't know of any plan to port mx to Python 3.
