Tucker, I've started a new thread for the OL + Closure testing I'm doing. If you want to test, I've created a simple project setup with an Ant build.xml: https://github.com/openlaszlo/openlaszlo-google-closure
Currently that's just an empty canvas being compiled to DHTML (or .lzi, if you add the "-S" argument). Check the code out into $LPS_HOME, and run "ant". With the .lzi file, the Closure compiler will complain about the pragma directives, with the DHTML JS code and the LFCdhtml.js I get "103 error(s), 244 warning(s)".
