10142	CKBuilder: Closure Compiler thinks native is a reserved keyword	Wiktor Walc		"It it impossible to build CKEditor after this change: [git:a2136ce] (native is a reserved keyword). I remember that it happened at least once in the past. We renamed the ""native"" variable to ""nativ"".

After a quick research it turned out we may get rid of this issue forever by using this piece of code:

{{{
options.setLanguageIn( CompilerOptions.LanguageMode.ECMASCRIPT5 );
}}}

native was a future reserved word in ECMAScript v3. Closure Compiler follows ES4, which also lists native as a reserved keyword.

However, I believe it will be quite unsafe to switch CC to ES5 mode at this moment, because this time we may not notice code that will be incompatible with IE7.
