I'm not an internals expert, but I think the difficulty in optimizing  
Ruby
method dispatch is that the result of a dispatch is not determined
by the local context but instead is determined by the state of all
the module objects searched during method dispatch:
	singleton class
	class and super classes
	included modules in all of the above
