Description Andrea Giammarchi 2010-09-09 11:28:32 PDT
There is no caller for *non* "use strict" cases when a getter/setter is invoked inside another function.
All other browsers work as expected and since the behavior of caller is undefined but you implemented in any case, I do believe WebKit/Safari should be more consistent bringing the caller in example cases as well.

See the URL for more tests or try this code:

var o = {
    exec: function exec() {
        var wtf = this.test;

o.__defineGetter__("test", function test() {
    return "test";

this is the reason I am asking for caller, hoping this will never disappear from ECMAScript specs.
