I know you could've done this with regular variables, but using pairs of colons to access the packages' $_s looks really funny:

perl -e '$::=$::::=($::==$::);map{$::::*=++$::;$::-=$::**--$::::>>$::}
+(++$::..++$::::**$::*$::);$::::+=$::*$::*$::+$::*$::*$::;$::::.=$::*$
+::::*++$::;@::::::=reverse($::::=~m/74|72|65|80/g);print map{chr}@:::
+:::;print"\n"'
