But this isn't terminating the end of a series of "options"; it's
terminating a series of assignments, and since env(1) detemines
whether an argument is an assignment or not by whether it has a '=' in
it, it makes sense to use '==' as David suggests.  It's different from
the others because it signifies the end of a different kind of
"series".
