Wouldn't it make sense to use a pre-processor for compiling python into javascript these days? There could be an standard library emulation layer.

For some use cases, sure. It isn't universal.

So, is this a plugin/extension of python, or a drop-in replacement of some sort in the vein of mariadb/MySQL?

It's a Python interpreter. You replace your current Python with it and run your code on top of it

Ps. Don't actually literally replace your Python, it will break your OS

I don't understand. How does this reference counting GC work? Last I heard about it, if won't collect circular dependencies. Yet here it is, used in Python, in Swift...

Ah, that's super-ugly. Basically, GC is creeping into the code. And it still seems to assume you somehow know when you write a class how all other classes will relate to it (then again, maybe the compiler may raise a warning/error if it detects a strong cycle).

Oh well, at least I have my answer.

Python also has a concept of weak references which you would use so the circular reference only exists momentarily
