What I think I remember hearing from Tom is that Dave's main point,
and the main argument with Tom, was precisely allowing proxies to
intercede on === checks, in which case you wouldn't even have that as

Hmm, maybe -- but does Self have a reference-identity
equivalence-relation operator that can't be spoofed? Might help to ask
David, but to abstract from that particular SPLASH 2011 Q&A, obviously
we won't be enabling such fakery in JS.
