Compatibility

This polyfill has following few limitations.

• WeakMap iterable argument is not supported. (23.3.1.1 WeakMap ( [ iterable ] ))
• Frozen and sealed objects are not supported.
• The values held by a WeakMap can't be collected once the map itself is GCed, since the values here are tied to the keys. #4
