No, it does NOT work. Because you can't ask all module/library authors
write like that. And that means even such modules should be work in old
browsers with ES6-shim, they actually fail just because a simple name
problem.


And, ES6 and any future version of this language already impaired by legacy
browsers. For example, typeof null MUST be 'object'.
