* 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
