You don't have to repeat the type parameters. This is not a compile-time error.

Removed

   Link.create();
 }
 
-class LinkFactory {
-  // Compile time error: should be Link<T>.create().
+class LinkFactory {   

[ahe, 2011/12/15 09:02:13]

However, this is a compile-time error.

Added

   factory Link.create() {
     return null;
   }
