Insert a newly created object of the (template parameter) type `TARGET_TYPE`, constructed by forwarding the specified `allocator` (if required) and the specified (variable number of) `arguments` to the corresponding constructor of `TARGET_TYPE`, into the array at the specified `toBegin` address, shifting the elements from `toBegin` to the specified `toEnd` address up one position towards larger addresses. If an exception is thrown during the in‐place construction of the new object, the elements in the range `[toBegin .. toEnd)]` are unaffected; otherwise, if a (copy or move) constructor or a (copy or move) assignment operator throws an exception, then any elements created after `toEnd` are destroyed and the elements in the range `[toBegin .. toEnd )]` are left in a valid but unspecified state. The behavior is undefined unless `toBegin` refers to sufficient space to hold at least `toEnd ‐ toBegin + 1` elements.
