and just to push this a bit:
some months ago i have submitted a patch to pd (in the sf 
patchtracker), that introduces to new dollar-arguments: $@ and $#.
while $# is probably not so interesting (now that we have [list 
length]), $@ is very similar to iemlib's [dollarg] but can do even more 
(e.g. full list expansion in a message)

if a lot of people find this useful, and at least some of them go 
throught the patch and find any bugs, probably it would be accepted 
into vanilla pd one day.
(i think it is already in pd-extended)
