By the way, this is not just some esoteric synthetic example. A type which is
copy-constructible but not copy-assignable is very useful to model immutable
objects.

Complete example:
#include
struct X {
X();
X(const X&);
X& operator=(const X&) = delete; // !!
X(X&&) noexcept;
X& operator=(X&&) noexcept;
int data = 54;
};
void
