	To clarify for anyone who is puzzled:

The most basic equivalence = these two references
indicate the same physical bytes in memory. Equaller
than that you cannot get.

Higer level equivalence = generally means that these 
two objects could be swapped without any side effects 
that are visible through the external interface they present 
to the world.
