(Reposting to get it on the mailing list; first try bounced.)
Hey, Matt, I agree with your analysis about the code-splitting issues. I've worked out a preliminary patch to do var renaming, but I haven't shared it yet because it's in a pretty early state. I could share it if you or someone is eager enough to see it that you're willing to hack some code to get to use it. To really get it polished up into a committable state, the main issue will be figuring out when to enable the rewrites. Whether to enable it or not depends on the choice of linker. For the off-domain loading, I was thinking to look into a JSONP-like downloader. That, too, is something that should only optionally be enabled, because it has worse download failure reporting. Thus, again the hardest part will be figuring out when to enable it. -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
