In older browsers like "Android 4" (pre-kitkat) and Google Chrome 12.0.x (haven't tested the "up-to" value) Intl.js throws

Uncaught SyntaxError: Unexpected strict mode reserved word

first at #L4 ("global") and then at #L412 ("extends"). At this point i stopped counting...

Since the library's intention is exactly to back-port a modern functionality to older browsers, this issue should be addressed.

Current workaround is to remove the statement "use strict"; from the distribution script.
Will this hatch any dragons in Intl.js?
