Python 2 with Python 3 syntax support: Thauton

[awesomebytes]

Given the case: https://github.com/naftaliharris/tauthon/tree/v2.8.0#tauthon

Tauthon maybe would be useful to be able to use some Python3 libraries in Python2... given the robot libraries are only available for Py2, it's a way to keep compatibility (which probably can be avoided by just exposing the robot APIs with a proxy, but I may be forgetting use-cases where this would become more useful).
