Almost the same situation with named FunctionExpression: (function () { var watch = 0; (function f() { alert(watch); //-> native code... })(); })();

That's ... bad! It seems Firefox decided to let the activation object inherit from Object.prototype. There is nothing in the specification that requires this, and, as you show us, it can give problems. Neither Opera nor IE does this.

No, Lasse, it is "special" object in scope chain created to keep FunctionExpression name only (ES 13), no bug here.
