/*
An example of the failings of <E extends Comparable<E>>:
-A is comparable to A, and B extends A (so B is comparable to A as well).  So far so good.
-we have 'someMethod()' that takes some generic type E where <E extends Comparable<E>>
-we call someMethod() and pass in 'new A()'; A implements Comparable<A>, so it works
-we call someMethod() and pass in 'new B()', which does NOT work: B implements Comparable<A>, which is no good
