Hello! I'm currently embedding Python in C++ and now having some problems with std::vector.
I used indexing suite to wrap it and work with it in Python like a Python list. But there is a problem: when I copy it in Python style (e.g. a[:] = b) it seems like it copies elements recursively, here is a log of copying:

Copy constructor
Copy constructor
Destructor
Copy constructor
Copy constructor
Copy constructor
Destructor
Destructor
Copy constructor
Copy constructor
Copy constructor
Copy constructor
Destructor
Destructor
Destructor
..

This is a real problem when the number of elements is more than 100000, because it takes a long time to finish. Is there anything to do with it?
