$ready works incorrectly

[tnhu]

var App = Class({
    $ready: function(clazz, api, parent) {
      var fromSubClass = (this !== clazz);

      console.log(this !== clazz);

      if (fromSubClass) {
        api.main.call(clazz);
      }
    }
  });

var Foo = Class(App, {
   constructor: function(foo) { this.foo = foo; },
   main: function() {
      console.log(new Foo("heloo").foo);
   }
});

main is not executed in App's context.
