I ran the formatter on this one only to have to scrunch up parameters. Will
change.

+        + symbol.getOriginalSymbolName();
     ClassElement classElement = (ClassElement) symbol;
     String name = classElement.getName();
     String nativeName = classElement.getNativeName();

       String mangledClassName = mangler.mangleClassName(classElement);
       jsName = globalScope.declareName(mangledClassName, mangledClassName, name);
     } else {
       jsName = globalScope.declareName(nativeName);
     }
     // Class names are globally accessible.
     jsName.setObfuscatable(false);
     names.put(symbol, jsName);
     assert !jsName.getShortIdent().equals("Object$Dart") : "unexpected " + ((ClassElement) symbol).getNode().getSource().getName();

   void setName(Symbol symbol, JsName name) {
