The typename keyword can be found in the draft standard. It is used
in template declarations to indicate that the following item is a
type. It is used in several places in the library definitions in a
construct like the following:
// class T is assumed to define a type xx
template <class T> class U
{
typedef typename T::xx xx; // Makes xx same as type xx in class T
...
}
