No, I don't agree. Virtual functions don't affect the code flow; they are just syntactic sugar for dynamic dispatch, but the code flow is the same as with other ways of doing dynamic dispatch (no matter if C++, C or Rust). But, uh, we're now even more off-topic, you're dragging me away from the topic (=RAII) so much, that I'm confident you're just a troll, and I've already been feeding you too much, shame on me. That was unexpected on LWN.
