-rw-r--r--

Implement a real Private Browsing Mode condition by changing the API/ABI;
This solves Tor bug #9701, complying with disk avoidance documented in
https://www.torproject.org/projects/torbrowser/design/#disk-avoidance.

 // arrow functions have an 'arguments' binding, like any other function

 var arguments = [];

 var f = () => arguments;

 var args = f();

 assertEq(args.length, 0);

 assertEq(Object.getPrototypeOf(args), Object.prototype);

 args = f(true, false);

 assertEq(args.length, 2);

 assertEq(args[0], true);

 assertEq(args[1], false);
