This is at best useless, and at worst harmful. If we start using languages other than English for code, then we'll end up balkanizing the software world. People in humanities departments can talk about things like "Chinese Poetry" and "Continental Philosophy," but in STEM, we should be above that nonsense. I should be able to read code written anywhere in the world and understand what it does. This is the same reason…
“Learning a new language” as in programming language, sits in the days-to-months range, while “learning a new language” as in Arabic takes months-to-years, so you’re building a much, much deeper chasm for others to cross and contribute, even though the source code remains English-based.
You can already see this happening with some open source libraries coming from China, where the documentation and all discussion being in ZH already completely blocks foreign contribution.
