/**
 * @brief Register the type T for direct serialization within Boost.MPI
 *
 * The @c register_serialized function registers a C++ type for direct
 * serialization within Boost.MPI. Direct serialization elides the use
 * of the Python @c pickle package when serializing Python objects
 * that represent C++ values. Direct serialization can be beneficial
 * both to improve serialization performance (Python pickling can be
 * very inefficient) and to permit serialization for Python-wrapped
 * C++ objects that do not support pickling.
 *
 *  @param value A sample value of the type @c T. This may be used
 *  to compute the Python type associated with the C++ type @c T.
 *
 *  @param type The Python type associated with the C++ type @c
 *  T. If not provided, it will be computed from the same value @p
 *  value.

/**
 * @brief Registers a type for use with the skeleton/content mechanism
 * in Python.
 *
 * The skeleton/content mechanism can only be used from Python with
 * C++ types that have previously been registered via a call to this
 * function. Both the sender and the transmitter must register the
 * type. It is permitted to call this function multiple times for the
 * same type @c T, but only one call per process per type is
 * required. The type @c T must be Serializable.
 *
 *  @param value A sample object of type T that will be used to
 *  determine the Python type associated with T, if @p type is not
 *  specified.
 *
 *  @param type The Python type associated with the C++ type @c
 *  T. If not provided, it will be computed from the same value @p
 *  value.
