dings are build directly
        on top of the C++ library, and nearly every feature of C++ library is available
        in Python, hybrid C++/Python programs using Boost.MPI can interact, e.g.,
        sending a value from Python but receiving that value in C++ (or vice versa).
        However, doing so requires some care. Because Python objects are dynamically
        typed, Boost.MPI transfers type information along with the serialized form
        of the object, so that the object can be received even w
