In that case, I have no qualms about proposing that unset 'a[@]' and

relying on the current behavior will just have to change their script.

   So echo ${a[@]} = expansion of all, but
unset a[@] would only delete 1 element w/key '@'....
how do I echo 1 element with key '@'

Creating arbitrary definitions of behavior for the similar syntax
seems like a sign of random feature-ism.
