When you type a Control-D, it simply terminates the input; the Control-D character does not get passed in as input. Anyway, if you rewrite your loop, you don't need to check for Control-D: 
while($picks = <STDIN>) {
  chomp($picks);

  # do stuff
}

<STDIN> will return undef when there is no more input on STDIN.
