'-l' has a dual nature - on input it behaves like chomp(), automatically removing newline characters, while on output, as we've seen, it becomes the anti-chomp, adding newlines. For completeness, I would mention that '-l' is implemented by messing with $\ and $/:
Also, you can specifiy a different character (in octal) on the command line for -l to use for $\ (output records):
-0 can also take an octal number, but this time it sets $/ (input records):
