Implement the notions of the "current instantiation" and "unknown
specialization" within a C++ template, and permit name lookup into the
current instantiation. For example, given:
template<typename T, typename U>
struct X {
typedef T type;
X* x1; // current instantiation
X<T, U> *x2; // current instantiation
X<U, T> *x3; // not current instantiation
::X<type, U> *x4; // current instantiation
X<typename X<type, U>::type, U>: *x5; // current instantiation
};
