I *think* the point is that OP expected that: (a) ${!var[@]-foo} expands to the indexes of var if ${var[@]} if set, else to `foo' whereas the behavior they observed is: (b) ${!var[@]-foo} expands to the value of the variable whose name is stored in ${var[@]} or to `foo' if that variable is unset Their expectation seems reasonable since "the variable whose name is stored in ${var[@]}" is kind of a weird thing.
