Re: template parameter representation

Greetings Alf,


I had an inspiration.

Somewhere along the way, I need to revisit at a minimum Modern C++
Design. At times the various policy, Traits, etc classes tend to get
blurred in my mind. In any event, given the desire to use a different
implementation beyond hw_default all the end use needs to do is add a
new trait, so now:

template < typename U, typename en, unsigned long base, unsigned
offset >
 struct traits< whatever_else <U,en,base,offset > > //NOTE:
whatever_else here..
 {
   typedef typename strip_pod_type<U>::type interface_type;

 };

template < typename UnsignedType,
           typename default_policy = no_policy < UnsignedType > ,
           unsigned base = 0, unsigned offset = 0 >
struct whatever_else {
// Add the stuff that needs to be 'different' from hw_default.

};
Carry on from there.
Mark
