Trojan Source and Python

I'm afraid that's unrealistic. That would prevent, for example, the inclusion of URLs in comments, because https is written with Latin characters. Same if you want to read or write files with some usual extension such as .csv, which also requires Latin characters. So, Latin characters should be allowed at least in comments and string literals.

I think it's important for those of us whose native language is written using a Latin script to keep in mind that we're the only ones who can (and will, unless we take explicit steps like learning a non-Latin language) live happily in a mono-script environment. Speaker of languages using other writing systems just don't have that option if they want to use a computer / the internet, as you can't do that without Latin characters. (Same goes with directionality: speakers of LTR languages are the only ones who can live happily in a mono-directional environment, speakers of RTL languages just don't have that luxury.)

There's a fundamental asymmetry here, which like most others, is all too easy to ignore when we're on the privileged side of it.
