Doing this, you lose the ability to provide the list of indices you're
interested in in the form of an array. This list couldn't be arbitrary

"${*}" expansion is also necessary in other situations than when
assigning to variables. It must be possible to still specify "${@}"
and "${*}" expansion explicitly.
