DefaultEquality<E> class
Equality of objects that compares only the natural equality of the objects.
This equality uses the objects' own Object.== and Object.hashCode for the equality.
Note that equals and hash take Objects rather than Es. This allows
E to be inferred as Null in const contexts where E wouldn't be a
compile-time constant, while still allowing the class to be used at runtime.
