// [basic.types]/10:
// Scalar types, trivial class types (Clause 9), arrays of such types and
// cv-qualified versions of these types (3.9.3) are collectively called
// trivial types.
// [class]/6:
// A trivially copyable class is a class that:
// * has no non-trivial copy constructors (12.8),
// * has no non-trivial copy assignment operators (13.5.3, 12.8), and
// * has a trivial destructor (12.4).
// A trivial class is a class that has a trivial default constructor (12.1)
// and is trivially copyable.
