I'm not completely sure what you mean here.
My first attempt was something like:

template<typename T>
model_generic_invocation<T>::visit (visitor *v)
{
  v->visit_generic_invocation ( (T *)this, ...);
}

I need to provide enough information in the
parameters for visit_generic_invocation() here
so that the dummy implementations can call
the appropriate visit_xxx() methods with the
required information, so that the existing
visitors don't break. However, without knowing
the actual instantiation for 'T', I can't seem to
extract this information. :-/

Ranjit.
