Hi Terry,
Thank you for you detailed email.
If two collections are equal, should the iteration order be the same? It has
always been true that if hash values collide, insertion order matters.
However, a good hash function avoids hash collisions as much as possible in
practical use cases.

Documentation that takes ten pages to say something is just as bad as
documentation that leaves stuff out, because it's almost guaranteed
that it won't be read.
That's the point. If a simple example (6 lines) can demonstrate the
concept, why spending ten pages to explain it. My experience is

Underlying problem: while unordered means conceptually unordered as far
as the collection goes, the items in the collection, if homogenous
enough, may have a natural order, which users find hard to ignore. Even

If you need the same ordering in two lists, you really should sort the
lists - though your comparison function need not be that traditional. You
might be able to get away with not sorting sometimes, but on CPython
upgrades or using different Python interpreters (Pypy, Jython), it's almost
certain
