You don't have to override "=" in the public part of a spec, so I usually don't.
With the strawmen I took the principle that only the public part of the spec was
presented, along with some extra stuff in the private part to get it to compile.
Perhaps in this case I took the principle too far...

I should shoulder the blame for any confusion this "implicit requirement" has
caused, since I left it implicit. But nits aside, it should be clear that "=" is
available, for Lists and Iterators, and thus implementors must make them both do
the sensible thing. Leaving them available but doing useless things is obviously
not good design. I might accept it for a package internal to a project, but
certianly not for something that is supposed to be standard.

Looking back at it now, what I should have done is what was done in the LRM for
the built-in operators in package Standard: put them in the public part
commented out.
