Is it possible to use a hash variable in a for-loop?

[Peng Yu]

Hi,

The following examples shows that a hash variable array[x] can not be
used in a for-loop. I think that if a regular variable can be
supported, a hash variable may be supported, too. Can this feature be
added? Or I have not used the correct syntax of this feature? Thanks.

$ declare -A array; for array[x] in a b c; do echo ${array[x]}; done
-bash: `array[x]': not a valid identifier
