Competence is always nice sure, but I don't understand how destructors help. They aren't invoked unless an object is destroyed, which it won't be if it paricipates in a cycle.

I think you understand pefectly :)

If you're accepting callbacks and storing them in an object, you can made a practice of using PadWalker and checking for closures

A slightly simpler check could be made using Devel::Refcount but why bother when PadWalker can do it :)
