I found the following approach, which already seems to be pretty
compact:
if [[ ${@[-1]:--} != -* ]] # If last argument is present, but does not
start with a dash
then
argv[-1]=--use=${@[-1]}
fi
slave "$@"
In the cases I tested, this seemed to work well. If someone thinks that
my solution is flawed, or come out with a better one, I would be glad to
know.

To cover the case of no arguments at all, here's a tweak to the answer
I posted yesterday:
setopt extendedglob
(( $# )) && argv[-1]="${argv[-1]/(#s)(#b)([^-])/--use=$match[1]}"
slave "$@"
