Or since Proxy traps correspond 1-to-1 to the "internal methods" in the spec, the primary goal of the Reflect API was to expose the essential methods that make up Javascript's object model as defined by the spec. There are many utility methods one may want to add on top, but it seems better to wait and see what the community comes up with rather than to try to codify an extensive API before it has seen any significant use. Regarding duplicates: ES6 has Sets. It should be fairly straightforward to adapt the above example to de-dup inherited property names. Regards, Tom
