In many cases, holding properly encapsulated resources using RAII "owning" objects can eliminate the need to write these operations yourself. (See Item 13.)

Prefer compiler-generated (including `=default`) special members; only these can be classified as "trivial," and at least one major standard library vendor heavily optimizes for classes having trivial special members. This is likely to become common practice.
