That explanation makes no sense to me. hive is substantially different
from other containers that I don't
know what concept you're talking about. Same goes for "patterningly"
and "practically".

I don't think it's in any way a normal thing to do with a hive.

Do we have a hive implementation that has field experience with an operator==?

Ah, like std::sort doesn't need to require a randomaccessrange, just
don't ever call it on a std::list? :)

I fail to see the difference. hive makes particular trade-offs to
achieve its semantics and its performance guarantees,
and this is one of them. It arises out of the concept of the
container, and is therefore not just an implementation detail.
