Long term, I would like to get these kinds of method removed from the element
hierarchy.

     if (!isResolved && !isBeingResolved) {
       isBeingResolved = true;
-      compiler.resolveType(this);
+      compiler.resolveClass(this);
       isBeingResolved = false;
       isResolved = true;
     }
     return this;
   }
