Move the elements of type allocator_traits<ALLOCATOR>::value_type in the specified range [fromBegin .. fromEnd)] into the uninitialized array beginning at the specified toBegin location, using the specified allocator to supply memory (if required), inserting at the specified position (after translating from fromBegin to toBegin) a newly created object constructed by forwarding allocator (if required) and the specified (variable number of) arguments to the corresponding constructor of the target type, ensuring that the specified fromEndPtr points to the first uninitialized element in [fromBegin .. fromEnd)] as the elements are moved from source to destination. On return, the elements in the input range are invalid, i.e., their destructors must not be called after this operation returns. If a constructor throws an exception during this operation, the output array is left in an uninitialized state. If an exception is thrown during the in-place construction of the new object, the input array is unaffected; otherwise, if a (copy or move) constructor throws an exception during this operation, the input elements in the range [fromBegin .. *fromEndPtr)] are left in a valid but unspecified state and the remaining portion of the input array is left in an uninitialized state. The behavior is undefined unless fromBegin <= position <= fromEnd and toBegin refers to space sufficient to hold fromEnd - fromBegin + 1 elements.
