/* * * 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 *
