I'm not sure if this actually improved over the status quo. A friend  
template such as

   template<typename T> class vector;

is still introducing a class template named "vector" into the current  
scope, so that template-ids referring to that template in that scope,  
e.g.,

   vector<T>

refer to a different class template "vector" than they would if the  
friend template were not present. This led to some really weird  
spurious diagnostics (of the "out-of-line definition does not match  
any declaration in..." kind) in some code I've been trying to parse.  
When the friend templates caused a compiler crash, it was easier to  
comment out that code to limp through ;)
