+The concept of shipped qty is sadly not as straight forward as it sounds at
first glance. Any correct implementation must in some way deal with the
following problems.

to record item links it's natural to assume that each position is linked, but
for various reasons this might not be the case. Positions that are not linked

+Save the C<shipped_qty> and C<delivered> state to the given objects. If
+L</calculate> was called with objects, then C<write_to_objects> will use these.
+
+C<shipped_qty> and C<delivered> will be directly infused into the objects
+without calling the accessor for delivered. If you want to save afterwards,
+you'll have to do that yourself.
+
+C<shipped_qty> is guaranteed to be coerced to a number. If no delivery_order
+was found it will be set to zero.
+
+C<delivered> is guaranteed only to be the correct boolean value, but not
+any specific value.
+
+Note: C<write_to> will avoid loading unnecessary objects. This means if it is
+called with an Order object that has not loaded its orderitems yet, only
+C<delivered> will be set in the Order object. A subsequent C<<
+$order->orderitems->[0]->{delivered} >> will return C<undef>, and C<<
+$order->orderitems->[0]->shipped_qty >> will invoke another implicit
+calculation.
=item C<shipped_qty>
