I applaud the effort that was taken to build this, but I would hope that none of my devs would approach me with wanting to implement inheritance in js. IMO the use case is very very small.

I saw a presentation on this and the performance increase was not even an advantage with prototypes because you would have to call a js function 10,000s of times to gain anything.

Agreed. Although benchmarking performance, in my opinion, is more of a study than a programming advantage. It's to affirm that a model does indeed work without flooding the system with memory intensive operations. The goodness an inheritance model brings has more to do with simplifying code rather than performance.
