But if you're not using a VCS safety it can be a dangerous thing.
Nothing pisses me off more than to get someone's code that has functions (comments) and files with dead wood - except maybe when I get 10 copies of the same file, each different, scattered throughout directories and subdirectories where you have to dig to find out which one is "current".
Ok, I take that back. Even worse is when someone goes in the database and creates tables or procs that were meant to be temporary and doesn't remove them. Only thing worse than dead code is dead junk in the database.
