   * To find an object to a verb, look for objects among effective children of a verb (''$child->get_attr('afun') eq 'Obj' ''). That implies working on analytical layer.

+  * Once you have node ''$object'' and node ''$verb'', use method ''$object->shift_before_node($verb)''. This method takes the whole subtree under node ''$object'' and counts the attributes ''ord'' (surface word order) so that all nodes in subtree under ''$object'' have smaller ''ord'' than ''$verb''. That is, the method rearranges the surface word order from VO to OV.

 **Motivation**: In dependency approach a question "where to hang prepositions" arises. In praguian style (PDT), prepositions are heads of the subtree and the noun/pronoun is dependent on the preposition. However, another ordering might be preferable: The noun/pronoun might be the head of subtree, while the preposition would take the role of a modifier.
