This method does not currently work. I simply tried to calculate the size from start and finish pointers. When it did not, I investigated further and this was my founding:

This is when we get the iterator value this comes out:

`_Deque_iterator(const _Deque_iterator& __x) noexcept
   169 	       : _M_cur(__x._M_cur), _M_first(__x._M_first),
   170 		 _M_last(__x._M_last), _M_node(__x._M_node) { }`

And when it++ is done this is what happens behind:

operator++()
   189       {
   190    ++_M_cur;
   191    if (_M_cur == _M_last)
   192      {
   193        _M_set_node(_M_node + 1);
   194        _M_cur = _M_first;
   195      }
   196    return *this;
   197        }
