namespace std {
  template <class T> struct default_delete<T[]> {
    constexpr default_delete() noexcept = default;
    template <class U> default_delete(const default_delete<U[]>&) noexcept;
    template <class U> void operator()(U* ptr) const;
  };
}

template <class U> default_delete(const default_delete<U[]>& other) noexcept;

1

Effects: constructs a default_delete object from another default_delete<U[]> object.

2

Remarks: This constructor shall not participate in overload resolution unless U(*)[] is convertible to T(*)[].

template <class U> void operator()(U* ptr) const;

3

Effects: Calls delete[] on ptr.

4

Remarks: If U is an incomplete type, the program is ill-formed. This function shall not participate in overload resolution unless U(*)[] is convertible to T(*)[].
