Someone on the list will correct me if I'm wrong, but to clarify your
guess (which seems correct to me): Physical equality is a pointer
comparison -- i.e. "do these objects occupy the same memory location".
I have assumed that, by "Structural equality", they mean *shallow*
equivalence -- i.e. "do these objects have the same structure, but not
necessarily the same content". Is this correct?
