Description:
        Is there some syntax to return just the index portions of
        arrays?

        I can assign arrays via

        list=([5]=home [6]=work [25]=other)

        and get all the information out with

        declare -p list

        but there are times I'd like to iterate over an array by using
        its indices rather than just data:

        patchrev=([123456]=08 [444323]=01)

        There may already be some syntax to just return 123456 and 444323,
        but if not then maybe ${?patchrev[*]}?

        So then I could

        for patch in ${?patchrev[*]}; do
          echo "Version of patch $patch is ${patchrev[$patch]}."
        done

        Thanks,
             Mario
