Only allowing "." seems a lot simpler. If we use the locale dependant decimal point when we print numbers, what should we do when parsing numbers ? If the parser also uses the locale decimal point, then source code compiles differently depending on the locale. If the parser doesn't use the locale decimal point, then number>string string>number isnt identity anymore.
The solution would be to have 2 different words to parse number in "canonical source code form" and numbers in "locale dependant form". Also, the parser currently hardcodes "," as thousands separtor, but it's also locale dependant...
