 * NOTES
 * =================
 *
 * `PYBIND11_MAKE_OPAQUE` will mark the type as "opaque" for the pybind11
 * automatic STL binding, such that the raw objects can be accessed in Python.
 * Without this they will be automatically converted to a Python object, and all
 * mutations on Python side will not be reflected on C++.
