That describes the situation closely enough to correctly that I don't feel the need to elaborate, yes. I will say that /in theory/ I can do whatever I want; in practice there are significant barriers to integrate new tools into the build system I'm required to use that make it prohibitive to do so. There are complexities there which I don't care to describe, but the point remains, effectively, the only Python option I have available is CPython. -- https://mail.python.org/mailman/listinfo/python-list
