Just to say that I've solved all my problems. My own boost archive it's finally
able to serialize everything that is defined in terms of boost serialization into
my serialization infrastructure which finally maps everything into our supported

I had to do so because I need keep compatibility across different supported
languages, framework and architecture using formats like matlab native mxArray
or python native pyobject. Especially matlab was really important because now
I can "materialize" boost object in the matlab workspace very easily.

I'll check the possibility to freely release a boost archive that maps object
defined in terms of boost serialization, without using my serialization
framework of course, into matlab workspace using a set of Mex functions or a
very small API to use inside a Mex.

So far so good! Since I need to get dynamically the type name as string,
I have actually implemented the "stringify" of the type name via the code

  template< typename T >
  inline const char* type_name()
    return (char*)
#if defined(__GNUC__) && defined(__cplusplus)
      abi::__cxa_demangle( typeid( T ).name(), 0, 0, NULL );
      typeid( T ).name();

which of course uses the specific g++ demangler that follow a non standard way
(I'd to follow a similar approach for the MSVC). So, my question is does the
boost library provide a standard way to get the type name as string?
