The following program DOES compile.  Your probably right that I
needed less.  I remember I tried to make something of wider
applicability than the serialization library.   Actually, its easier
on my brain to think in terms of something more general
than think in terms of the more narrow needs of a particular
application. Its intriguing to me that no one has made a real Boost
version of something like this as I need it from time to time.

#include <boost/strong_typedef.hpp>

BOOST_STRONG_TYPEDEF(int, x_t)

main(int argc, char *argv[]){

x_t x1 = x_t(1);

x_t x2 = x_t(2);

x_t x3;

x2 = x1 + x2;

}
