It would also have the same limitation that "use strict"; does, which is 
that it doesn't play well with (the quite common pattern of) concat'ing 
minified scripts together in build environment deployments, because your 
"use stict" declaration in one of your files bleeds over (probably 
unintentionally) to affecting other files when they are all combined into 
one file.

Maybe something like:

use "sensible arithmetic" {
 // ..

Perhaps? In any case, I'm definitely not a fan of continuing the frustration 
that "use strict" gives us in concat-js environments.
