The sequence is now just mapped to std::vector as returned by value. By 
using the C++11 move semantics you can prevent easily a copy at that moment

All _ptr/_var/_duplicate calls are gone. Argument passing is by value 
for basic types, object references, and enums, all others are passed by 
reference.

We have limited it to the minimal, local objects and servants you have 
to create with new and than you transfer ownership to the object 
references. For anything else, it is not required anymore.
