I'm interested in seeing how source maps can work for evalled script. This is in order to bring support to the RequireJS CoffeeScript parser. One way I've been experimenting with this is through data-uris in the @ sourceMapperURL property.

When testing this with eval code, it seems that this method is working correctly. The only issue I have is that the @ sourceURL property is displaying the js file not the coffeescript file in the sources window, even though the debug line points correspond to the coffeescript file. If this could be fixed so that when a @ sourceURL and @ sourceMapperURL are both present in evalled code, the @ sourceURL code is displayed in full, that would be great.
