The question is rather when to consider a variable set or unset.

For me, an empty string (or empty commadline) is as set or as
unset as an empty array.  But I don't get an "unbound error" when
accessing an empty string (or empty commandline), and I get one
when accessing an empty array.

I can live with that behaviour, but it probably should be precisely
documented when a variable is set or unset for Bash.
