For instance, to insert after 3rd element, you would write

  O.engines=O.engines[:3]+[YourEngine()]+O.engines[3:]

(see http://docs.python.org/tutorial/introduction.html#strings, look for
"slice")

HTH, v.

PS. If you think it is really useful, vector<shared_ptr<Engine> > can be
wrapped specially to mimick all list operators, it would just be some
work that I can't do ATM.
