Calling this type is very confusing and has led to many newcomers thinking that it makes a new type when really it's just to save on typing (ha!) by making an alias.

I'm tempted to say it should just be like C++11 where you can do this:

using foo = int;
template<typename T> bar = std::set<T, std::greater<T>>;

If it's not feasible to extend use this way, calling it alias would still really be an improvement.
