Ok.. Some people will think is obvious and stupid, but others newbies like myself might find it interesting. Earlier this week, I learned something new looking at some code in the Camal book on how to get the date using localtime. It uses an anonymous array (??correct term??)of the days of the week to return the day based on the index return by localtime.
So trying this technique out myself i create the one lined roman numeral converter!!
#!/usr/bin/perl -w
# pass a number 1..10 to the program
print scalar(("I","II","III","IV","V","VI","VII",
"VIII","IX","X")[(shift)-1]);
Ok.. Stupid, but cool

UPDATE:
This can be reduced further following a suggestion from Fastolfe.
print [qw/ I II III IV V VI VII VIII IX X /]->[shift()-1]
