The same may be said for virtually everything else in C.

However, yes, some advanced template constructs need better compilers.
But that does not mean that every template construct is advanced.
No.  That does not reflect reality.

Certainly, I don't want to implement the same data structure in C++
each time the contained objet type changes.


   template<class T>
     struct list {
         list<T>* previous;
         list<T>* next;
         T        data;
     };

will work even with GCC-2.7.x.  It is -not- an advanced construct.
It has been in ARM C++.

Matt gave some thoughts on that issue.

Anyway, this is completely orthogonal to Tom's request.
