Thanks Benjamin for the reply and the suggestions. My doubts are not on
the design but in the logic of gcc and templates in general. In particular
I don't understand why in the templated version of my code the instruction

   DisplayTraits<_t>::process();

do not works (_t is a const int declared as private member variable) while

   DisplayTraits<t>::process();

works correctly (t is a const int declared inside the main() ).
In fact I do not want to declare Display as template since the function
f() must remain with its syntax.
I don't know if this is the correct mailing list but I thought that this
prolem could address well in standard c++ implementation related questions.
