I'm failing to see how equivalence and definition are different. (I know

The main confusion is between assignment and equality, generally. Or, in
mathematics, between a test for equality and a statement of equality.

You would first have to define the concept of fields being "the same". ;-)
Fortunately, in a pure functional language, the question becomes a lot
simpler.
