title: Rails how do I check for existance of a class when not instantiated yet?
body: <p>I have a utility class defined with a bunch of class methods.  In the Rails console, when I search for the class using <code>Object.const_defined?</code> it returns false.  But after calling one of the class methods or creating an instance of the class, <code>Object.const_defined?</code> returns true.  Is this because of some kind of lazy loading instantiation kind of thing?  Is there another way I can check for the existence of a class which will return true, even if I haven't instantiated anything yet?</p>
