Want copy semantics unless you're building a “sensible pointer”. Price semantics is the simplest to reason about and what the normal-library amenities count on.

We are well mindful that you might claim the “lousy” examples much more reasonable than the ones marked “Okay”,
use const consistently (Check out if member functions modify their item; Verify if capabilities modify arguments passed by pointer or reference)
