 * Date:    16 Dec 2002
 * SUMMARY: Testing |with (x) {function f() {}}| when |x.f| already exists
 * See http://bugzilla.mozilla.org/show_bug.cgi?id=185485
 *
 * The idea is this: if |x| does not already have a property named |f|,
 * a |with| statement cannot be used to define one. See, for example,
 *
 *       http://bugzilla.mozilla.org/show_bug.cgi?id=159849#c11
 *       http://bugzilla.mozilla.org/show_bug.cgi?id=184107
 *
 *
 * However, if |x| already has a property |f|, a |with| statement can be
 * used to modify the value it contains:
 *
 *                 with (x) {f = 1;}
 *
 * This should work even if we use a |var| statement, like this:
 *
 *                 with (x) {var f = 1;}
 *
 * However, it should NOT work if we use a |function| statement, like this:
 *
 *                 with (x) {function f() {}}
 *
 * Instead, this should newly define a function f in global scope.
 * See http://bugzilla.mozilla.org/show_bug.cgi?id=185485
