I like it. (Incidentally, I know of only one other language that
exploits @ being pronounced as "at".)
Is it correct that you can use at: only for numeric indices? I'd like to
use it for keys as well...

The wrapping process is not really part of the indexing IMHO. The idiom
of wrapping around isn't really common. So I don't see a reason to
include this; I think in this case the overhead to learn the symbol
outweighs the benefits.
YMMV of course...
