perl -lne 'END{print$x}$x+=$_'

Perl one liners are nice. Don't forget that, although perl is also an awesome fully-featured programming language, it's roots are as a command-line data-processing tool (ala sed, awk and even grep). Who wants to spend those extra characters in a -e?

Don't get me wrong, I like strict in anything more than a few lines long, but I also write a lot of stuff that's less than a few lines long.
