Construct a forward iterator from the specified `other` iterator of another (compatible) `ForwardIterator` type, e&period;g&period;, a mutable iterator of the same type&period; Note that this constructor may be the copy constructor (inhibiting the implicit declaration of a copy constructor above), or may be an additional overload&period;
