It would be nice to have an automatic mechanism for serializing the wrapped C++
objects. As it stands I have to manually define the pickle support for each
wrapped C++ type.

In practice it is not a big deal, though, at least not with my usage patterns.
Most of my wrapped types are never pickled. The only major effort was to
implement efficient pickling of large arrays.

Going off on a tangent: does the boost serialization library have support for
portable serialization of large arrays (e.g. std::vector<double>)?
