No, that's also disallowed. Bash variable names (including arrays) must
begin with a letter or underscore.

Shift already takes one optional argument: the number of items to shift

Do you put the optional list name first, or do you put the optional number
first? If only one argument is

This is the simplest and most elegant solution.

The biggest issue here is how you specify the arguments.
Shift
It struck me as it might be convenient if 'shift' could take an optional
arrayname as an argument. Would that be possible or would it cause some
incompatibility?
i.e.
set one two three four five
dcl -a ARGV=("$@")
shift ARGV
echo "${ARGV[@]}"
two three four five
shift 2 ARGV
four five
