In ES specs, there's no indication that [[Class]] can or should be used
for internal method lookup; I don't know where you got that idea.

As for implementation, [[Class]] could be derived from some other type tag
that gives sufficient information to do such lookup, but [[Class]] by
itself is not sufficient.
