[pooma-dev] Using template template parameters in new code ok?

[Stephen Smith]

That's all there is too it.  In fact, people had often commented that some 
code would
be cleaner with template template.  It is a pretty recent addition to many 
compilers.

Rather than write:

template <template <class T> class X>
class A { //...
    X<int> myFunctor;
};

We would define a requirement for an external traits-like class and use a tag:

template <class X>
class A { //...
   MyFunctor<X,int> myFunctor;
};

You'll find patterns like this all over POOMA.
