in thread Skip 21 Lines

Something I always use for the xth line of a file....
(undef,undef,undef,undef,$line) = <FILE>;
At the expense of reading the entire file and tossing all but one of the lines. Ouch!

    Isn't it more maintainable to write that as:
    $line = (<FILE>)[4];
        Yes, that was a joke.

        But if you are going to be inefficient, at least be idiomatically inefficient. I didn't like having to count through undefs to figure out which line you were grabbing...
