I can't help mentioning, because I was so happy when I stumbled across it, the following cute syntax for skipping a constant number of lines using the range operator:

while ( my $line = <$file> ) {
     next if 1 .. 14;
     do_stuff;
}

(Unfortunately, it doesn't work with a variable—for example, next if 1 .. $lines_to_skip—since the range operator just tests whether $lines_to_skip is a true value, not whether it's equal to $..)
