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;
Effects: constructs a default_delete object from another default_delete<U[]> object.
Remarks: This constructor shall not participate in overload resolution unless U(*)[] is convertible to T(*)[].
template <class U> void operator()(U* ptr) const;
Effects: Calls delete[] on ptr.
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(*)[].
