in reply to Re^2: Managing capture
in thread Managing capture
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 :)
