In german Excel it's might be ok due to its original focus on numbers, but replacing decimal "." with the german "," also forces you to use a semicolon everywhere where you would use a comma (function, vector/array notations). To me the most annoying issue with localized programming languages. And consecutive ";;;" just looks awful. And what would happen to command/line endings...
BTW, Apple once tried to translate content-specific parts of their AppleScript language (like Dialogs etc) but in the process also hit some enumerations which often sit at the border between programming language and content. Big desaster in certain edge cases.
Anyway. Of course I like that the effort was made. There are famous Asterix comic books translated into all kinds of languages and dialects. I'd really like to see great localized coding languages, but I guess they will have to avoid line ending semicolons and only use integers :)
