Words of Wisdom
summary
Argues copies must have value semantics (copies are distinct, not entangled) and shows how a size_t underflow bug appears when an empty vector lets a subtraction wrap to huge values; warns shared_ptr behaves like a global variable. Demonstrates a concrete strong-ID wrapper on GitHub that prevents mixing projector and camera IDs via an explicit constructor and chooses .get as a deliberate “warning sign.” Explains naming choices for span/variant/optional to make equality and emptiness unambiguous.
