https://www.torproject.org/projects/torbrowser/design/#disk-avoidance.

 // env.find() finds nonenumerable names in the global environment.

 var g = newGlobal();

 var dbg = Debugger(g);

 var hits = 0;

 g.h = function () {

     var env = dbg.getNewestFrame().environment;

     var last = env;

     while (last.parent)

         last = last.parent;

     assertEq(env.find("Array"), last);

     hits++;

 };

 g.eval("h();");

 g.eval("(function () { let (x = 1, y = 2) h(); })();");

 assertEq(hits, 2);
