In order to make a class work with associative arrays / hash 
tables, it will need to implement at least Hash and Equals. 
Similarly, any class that implements Ordered can and probably 
should implement Equals, too.

At the very least, Hash and Ordered should both extend Equals so 
that implementers don't have to waste another pointer on 
explicitly implementing Equals when it can be done implicitly 
just as well.
