[Help-bash] Why empty key is not allowed? |

Hi,
I am trying to assign an empty key to an associated array.
$ declare -A x
$ x[]=1
-bash: x[]: bad array subscript
But I got this error. Is it not allowed? Or I am not doing it correctly?
The manpage says this. So empty string should be allowed?
"associative arrays are referenced using arbitrary strings."
Thanks.
