javascript calling a function on window object
<p>I have the following code and am wondering how to make the last line work. I addopted a set of api's that current use _view appended as it's namespacing convention and would rather use something like arc.view.$function_name. thx</p>

<pre><code>var arc={};
arc.view={
  say_hello: function(){
    alert("I want to say hello");
  }
}
function say_goodbye(){
  alert("goodbye to you");
}

arc.view.say_hello(); // works
window['say_goodbye'](); // works
// possible to make this work?
window['arc.view.say_hello']();
</code></pre>
