How to decorate any object in Ruby in 3 lines

Here is a quick and easy way to decorate any object instance in Ruby.

This is useful if you don't know or care the object type you are working with but would like to add accessor methods to just that instance. This is a very pure decorator because adding accessors does not rely on internal knowledge of the object.

We're just dynamically adding functionality to the instance as we need it.

NOTE: This could clobber existing functionality, so you want be sure you are decorating it with a method name that won't interfere with the object class.
