Rule 6.9.2: Are non-top level users of basic types permitted in an alias?

[gdavis]

Hi,

The first exception for Rule 6.9.2 permits the use of a basic type to define a type alias.  I guess the wording may be more broad than intended.  For example,is the following permitted?

Code:

#include <list>
typedef std::list<int> int_list;

Thank you!
