Every time I've been to a programming shop in a foreign country, the developers 
speak english at work and code in english. Of course, that doesn't mean that 
everyone does, but as far as I can tell the overwhelming bulk is done in english.

Naturally, full Unicode needs to be in strings and comments, but symbol names? I 
don't see the point nor the utilty of it. Supporting such is just pointless 
complexity to the language.
