Going with the theory that you never really know where the lines are until you step over them, I submit die"$0\n"
Of course, the file was named "Just Another Perl Hacker" ...

    I submit that the following is shorter:
    perl -pee
    Then start pressing the following keys: 'J', 'u', 's', 't' SPACE, 'A', 'n', 'o', 't', 'h', 'e', 'r', SPACE, 'P', 'e', 'r', 'l', SPACE, 'H', 'a', 'c', 'k', 'e', 'r', ENTER. Japhage magically occurs...

    If you are going to go through this trouble, name the file "Just another Perl hacker,\n" and then reduce it to:
    die$0
      Not quite. You need the "\n" at the end of the die() argument to keep it from spitting out the filename (again) and line number.

        I didn't miss that detail. Here is a Perl program that both writes and runs the script under Unix:
        my $filename = "Just another Perl hacker,\n"; open (OUT, "> $filename\0") or die "Cannot write '$filename': $!"; print OUT 'die$0'; close OUT; system "perl '$filename'";
        Do you see where the return is coming from now?
