This is a neat trick, the best I've seen for commenting out huge blocks. But yeah, there is no reason for commented out code. From "97 Things Every Programmer Should Know" http://programmer.97things.oreilly.com/wiki/index.php/Comment_Only_What_the_Code_Cannot_Say http://programmer.97things.oreilly.com/wiki/index.php/Commen... > Commented-out code is not executable code, so it has no useful effect for either reader or runtime. It also becomes stale very quickly. Version-related comments and commented-out code try to address questions of versioning and history. These questions have already been answered (far more effectively) by version control tools.
