Yeah, and even after it is assigned, it's more optimal to use the arg, since that means you can sometimes end up eliding the field, and even if you don't, it's a local reference instead of a 'this.' lookup. http://gwt-code-reviews.appspot.com/1339801/show -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
