It is mostly the "dependent type" problem, that is, when the type is not 
available until instantiation. E.g.


struct A {
  typedef int cheese;
};

template<typename T> 
struct B {
  typedef typename T::cheese stelton;
};

I had a book once that showed an example where not requiring the keyword could 
lead to the compiler picking the wrong definition of something, but I can't 
remember it offhand, and the book disappeared some time ago.
