Thank you for the reply! Do you know, is there's any noticeable overhead of frequent python::extract() calls? Is it urgent to have some pre-extracted data-structure on c++ side, or this is similar to having a pointer?
It will incur an overhead, since the python interpreter needs to be involved. So it's better to do this once, ahead of time, and preferably store all property map values in a single python object.
