Hi all,

here I have to disagree with Jeff - only the important part highlighted:

No one wants enumerated values to be equivalent - just the names of
enum items iff the corresponding enums are equivalent - and I think
that was clear from the text Kathryn sent around. So if I understand
your example correctly we have on both processes an enum
"network_info" with variable name "network_address" with the value
"A.B.C.D" on process A and "W.X.Y.Z" on process B. And I think this is
covered by our definition of having semantically the same behavior.

Am I'm missing a point here?
