__ES4__ is per default open in ES4 mode but not in ES3 mode, it's a
way to protect the ES3 namespace from being infected by names and
functionality that could break live ES3 programs.
intrinsic is on the other hand not open per default but has to be
specified explicitly, either in implicit::identifier form or through a
use implicit directive. Or that's my understanding of it, anyway.
