[array.cons]

26 Containers library [containers] 26.3 Sequence containers [sequences] 26.3.7 Class template array [array] 26.3.7.2 array constructors, copy, and assignment [array.cons]

The conditions for an aggregate shall be met. Class array relies on the implicitly-declared special member functions ([class.ctor], [class.dtor], and [class.copy]) to conform to the container requirements table in [container.requirements]. In addition to the requirements specified in the container requirements table, the implicit move constructor and move assignment operator for array require that T be MoveConstructible or MoveAssignable, respectively.

template<class T, class... U> array(T, U...) -> array<T, 1 + sizeof...(U)>;

Requires: (is_­same_­v<T, U> && ...) is true. Otherwise the program is ill-formed.
