Re: [C++-sig] preventing a copy of the vector when using the vector_indexing_suite

Sorry about my ignorance. Why do you define those implicitly convertble pointers?

It's required to make smart pointers work correctly to convert between classes in the same hierarchy I believe. There may be a cleaner implicit way to make them work, but this is the approach I took after reading through old postings, faqs and various boost::python/pyste doco.
