i want indexes of parameters,

and can get it by dummy var:

dummy=( $@ )
echo ${!dummy[@]}

but is there straight way to get them, something like

$!@ ... not working
$!* ... not working

... or something like that?

NOTE: original function that i want to have without arr var is this:

function indexof()
{  search="$1"; shift; arr=( $@ ) 
   for i in "${!arr[@]}"; do [ "$search" == "${arr[$i]}" ] && return $i; done
   return -1
}
