An ES2015 mostly-spec-compliant Reflect.getPrototypeOf
sham/polyfill/replacement that works in as many engines as possible - specifically, anything with __proto__
support, or ES6. Built-in types will also work correctly in older engines.
This package implements the es-shim API interface. It works in an ES3-supported environment and complies with the spec.
