And if you don't do that rename step, and edit a program, unpredictable
things happen. It's easiest to do with scripts. In the case of Perl, the
interpreter reads the whole thing and then runs, pretty safe. In the
case of Bash, it reads it line by line, so if the script changes
underneath it, it will likely read the next line from the wrong spot.
