Yes, I also think the whole word should program in English.

That's half tongue in cheek. I am fluent in three languages, but I program "in English" and I greatly appreciate that my colleagues who are fluent in languages other than the ones I'm fluent in (except English) also do. Basically English is the world's lingua franca today. Nonetheless if a company in France wants to use French for their symbol names, or a company in Mexico wants to use Spanish for their symbol names, or a company in China wants to use Chinese for their symbol names, who am I to stop them?! Surely it's not my place.
