probably other type of operators) of two strongly typed variables.

 If you add two strongly typed variables of the same type result is not of
 the typedef type but of the underlying type.

 The example below will generate a compiler error which is unexpected as I
 see it.

 #include <boost/strong_typedef.hpp>
 BOOST_STRONG_TYPEDEF(int, TypedInt)

 int main()
 {
   TypedInt x(10);
   TypedInt y(20);
   TypedInt z = x + y;

   return 0;
 }
