 handles => ARRAY | HASH | REGEXP | ROLE | ROLETYPE | DUCKTYPE | CODE
               The handles option provides Moose classes with automated delegation features.
               This is a pretty complex and powerful option. It accepts many different option
               formats, each with its own benefits and drawbacks.

               NOTE: The class being delegated to does not need to be a Moose based class, which
               is why this feature is especially useful when wrapping non-Moose classes.

               All handles option formats share the following traits:

               You cannot override a locally defined method with a delegated method; an exception
               will be thrown if you try. That is to say, if you define "foo" in your class, you
               cannot override it with a delegated "foo". This is almost never something you
               would want to do, and if it is, you should do it by hand and not use Moose.

               You cannot override any of the methods found in Moose::Object, or the "BUILD" and
               "DEMOLISH" methods. These will not throw an exception, but will silently move on
               to the next method in the list. My reasoning for this is that you would almost
               never want to do this, since it usually breaks your class. As with overriding
               locally defined methods, if you do want to do this, you should do it manually, not
               with Moose.
