Command line arguments are in the array named @ARGV. The diamond operator gets lines from whatever the current input file is.

If you get a line from a file and test it as in your examples, you will no longer have that line to play with. You want to fetch it into a variable and then do your tests, etc.

We're not really tightening our belts, it just feels that way because we're getting fatter.
