I am fully aware of the danger of polyfills and will update the README of the libary to point to the referenced article. That being said, I hold there are cases where polyfills may be the only choice, i.e. where instanceof semantics must be preserved or major portions of existing code will have to be re-written (introducing yet another set of risks). This library was designed in such a way that the programmer has the ability to select which polyfills to use and can take the risks in an informed manner.

However, we have found there are cases where facades and wrappers will not work, making polyfills or subclassing the only choice, i.e. where instanceof semantics must be preserved or major portions of existing code will have to be re-written (introducing yet another set of risks). We attempted to develop the library using subclassing; however, the Chrome engine does some internal checking on instances before method invocation and we were getting errors related to generic function calls and instances not being of the correct type. We will continue to endeavor to enhance this library so that it does not compel the use of a polyfill so that all choice is in the end developer's hands. Meanwhile, the library was designed in such a way that the programmer has the ability to select which polyfills to use and can take the risks in an informed manner."

I'd say that blog post lacks way too many examples, use cases and
serious studies to be called anything close to documentation.
That's more in the line of:
	X is not perfect so Y, which I personally like, must be used always.
Proof:
	X fails in one example.
