Is there something we can do to make it easier for people to deal with

there a pattern we can abstract out and provide as a tool or recipe for
people to use in their own code?
It sounds promising but so far a bit too vague for me to understand
what you're really suggesting. What form would this "something" take?
Are you envisioning, say, a function safe_recursive_iter so that you
could do `for item in safe_recursive_iter(obj)` and it would cleanly
raise an exception if it wound up recursing through the same object more
than once, rather than getting stuck in an infinite loop?
