Wow, cool. Thanks for sharing the link! (the code is in English, only the comments are in French)
One rather minor question: Is writing comments or even code in the local language still common in France? Afaik, in most European countries the CS courses are taught in English.
I mostly write my assignments in French. It just feels "strange" to me to write comments (which are just real sentences) in English when anyone which will read the thing shares my native language.
When I'm comment complex things (like some parts of this compiler), I feel it easier and more comprehensive to explain them in my mother tongue.
Anyway, I write all of my "public code" in English. The audience is different.
All the literature, programming libraries etc. have corrupted my brain to the point that I write my code in English when it's only for my own eyes, even though it isn't my native tongue.
