Both @ and @@ are also used in SuperCollider,

Which language do you have in mind? 

>The wrapping process is not really part of the indexing IMHO. The idiom

well, it just is damn useful in the above-mentioned
context (sound synth etc).  If you leave it out 
in a release you are bound to have just about every
user extend the system in his own way to provide
wrapping because they will use it all the time.
Plus, there is a number of very basic classes
for music / sound processing that make heavy 
use of wrapping, so you cant do without it.
