The mechanics of default arguments maybe, but that's tautological. If
you mean call-by-object, any time you pass both mutable and immutable
things around, you will learn the same lesson. If you mean the more
general principle that "Python doesn't ever copy things unless you
explicitly ask", working with lists (and particularly their
multiplication operator) again tends to also teach that lesson.

I disagree. Just add a keyword for each default argument evaluation
behavior (evaluate-once-at-definition-time [e.g. "once", "static"] and
evaluate-at-call-time [e.g. "fresh"]) and don't have there be a
default behavior; make the choice explicit. They'll be confronted with
the issue as soon as they're shown default arguments, and keywords are
easy to look up the meaning of.

And as I said previously, there are other common ways to learn any of
the "lessons" that default arguments might "teach".

If-I-had-my-druthers-ly yours,
