I have no idea what you mean by "equivalent" or "interchangeable".

In general, when I say that x and y are equivalent (or interchangeable), I mean that in any context in which x appears can use y instead with the same effect.

In the context of this particular discussion, I am talking about two objects being equivalent (in the sense above) in any program that does not directly determine the identity of those objects.
