It's Python 3.8, and I learn that in 4.0 "spam" is going to become a keyword. I simply take my code and change all the references spam to \spam, and I've future-proofed the code for 4.0 while still keeping compatibility with 3.8 and 3.9.

Okay, maybe it helps a little bit, but not very much. There
will still be a lot of reluctance to add new keywords, because
of the disruption it will cause to existing code

And the alternative is to replace all occurrences of

spam with 𝐬𝐩𝐚𝐦 , which has the same effect and also is backward-compatible with

3.x for x < 8.

So there is already a kind of solution available, albeit an ugly one.

If we've learned nothing else from the Python 3 changeover,
it's that many people work in an environment where it's
extremely difficult to update working code.
