    Description

      this is a bug / feature-request

      current implementation of containers requires copying of eg. vector each time it is accessed in python.

      shiboken should implement a way to expose eg. vectors(by pointer / ref)  that expose python's list defs(methods)

      that vector would behave 'almost' same as pythons native list but wouldnt need to be copied.

      pybind11 allows that :  https://pybind11.readthedocs.io/en/stable/advanced/cast/stl.html#making-opaque-types
