title: Is there a way of obtaining all library objects within an instance of JS?
body: <p>Is there a method in which I can iterate through all objects that exist within an instance of JavaScript, regardless of the JavaScript engine that is being used?  I'm not interested in iterating through the DOM of a web page.  What I want to know is if there is a way that I can iterate through all standard library objects (Array, Math, Date, etc.) as well as any additional libraries that may be specific to various browsers.</p>
