You break your own argument here. From the caller's point of view, a call appears atomic, but thanks to AUTOLOAD, the call itself is able to modify the world, even before the eventually-installed method is entered. You can stop time just before the call, and still not prove what methods are available. QED.

And words are important: I said 'akin,' not 'equivalent.' There are differences. However, they're both in a group of unprovable-because-the-domain-can-change problems.
