Thanks! With your change the example works. Unfortunately I'm still
confused.
Before I reduced the code to a short example I was using
Object.getPrototypeOf(obj), like:
https://gist.github.com/johnjbarton/30c3e72d51d9d64e36d1
rather than targt[name] my first examples shows. It also fails the same
way.
Let me rephrase my question: why is the Proxy get even called in this case?
