How about a new property for class and struct to get the fully qualified name?

[Heromyth]

How about a new property for class and struct like `.stringof` to 
get the fully qualified name?

I know the `fullyQualifiedName` can do this. If a new property 
like `.qualifiedName` added to class and struct, the code blown:

     @Middleware(fullyQualifiedName!(IpFilterMiddleware), 
fullyQualifiedName!(BasicAuthMiddleware))
     @Action string security() {
         return "It's a security page.";
     }

may be changed as：

     @Middleware(IpFilterMiddleware.qualifiedName, 
BasicAuthMiddleware.qualifiedName)
     @Action string security() {
         return "It's a security page.";
     }

It looks better, does it？
