That's like saying that Mac Lisp still works because you can put soldering iron to work and resurrect on of the two remaining Lambdas in existence.
The whole point of what I said is that it doesn't work on modern systems. If you emulate old systems where it worked, then it's a nobrainer that it will work. Like, what are you even trying to prove with this?
They can still be built in a suitable build environment (which is easy eg. with a container, and it is trivially easy to install a python 3.7 environment on a current linux, using precompiled binaries, without impacting the systems current python version, thanks to `pyenv`
In fact I could install all the way down to 3.0.1 if I wanted (and ofc Python2 versions).
