Thats exactly why I don't understand why 2.7 was chosen for Mystic Python lang.
2.7 was chosen long before the end of life when it was still the default version use in every major Linux and OSX release. You had to go out of your way to install Python3 at the time.
But also because of technical reasons. Python 2 has compatible codepage and string handling with Mystic, and Python 3 does not. You'll have to have a strong understanding of encoding to effeectively use Python 3 with Mystic and many people get a little lost with that stuff.
... Everyone has a photographic memory. Some don't have film.
