I don't think V8 has support for fast access of property attributes at the
moment. But I have the feeling that duplicating all of the attribute checks
in
the builtin functions is the wrong approach since we are able do them in
the ICs
already.
So for this particular instance you can just switch Array.prototype.reverse
into
strict mode and get the desired behavior. But I don't want to land a change
that
switches just Array.prototype.reverse into strict mode before we thought
through
all affected builtin functions first.
Also it's not trivial to just switch all our builtin functions into strict
mode.
