I pushed my current progress on source maps into the flex-falcon develop branch today. I still have more work to do (and many more tests to write), but things are coming along nicely.
Source maps will let us debug in the web browser using the original ActionScript instead of the generated JavaScript. Simply add the --source-map argument to your compiler arguments to generate source maps for your classes. The files in "js-debug" will map back to their original ActionScript. Your browser's developer tools should know what to do automatically! I've mostly been testing in Firefox, but a quick test in Chrome not too long ago looked good too. - Josh
