template<typename T> class A{};
template<typename T> class B{};
template<typename T> class C{};
template<typename T> class D{};
template<typename T> class E{};
template<typename T> void f() {
typedef A<typename B<D<E<int> > > > foo;
}
gets you:
~/ootbc/members/src$ g++ foo.cc
foo.cc: In function `void f()':
foo.cc:7: error: template argument 1 is invalid
foo.cc:7: error: ISO C++ forbids declaration of `foo' with no type
In template metaprogramming spaghetti, it would sure help if the diagnostic
said just *which* template invocation had argument trouble.

If we used the caret way of doing things it would just work.
