Fair enough. I don't need line numbers specifically when I have a full-on in-browser graphical debugger so I can debug exactly what is being interpreted. There's work underway to handle mapping back to source files, and when that arrives, it will be "nice". However, listening to NodeUp podcasts, people think that line numbers not lining up is an absolute deal-breaker, which I just don't find to be the case at all in my personal experience.
