More of this comes back to me ... I think the situation is/was this:
hash=( [Y]=why [0]=zero )
echo $hash
zero
That is, reference to the entire hash without subscript returns a
reference to the element with key "0", just as reference to an array
without subscript returns the 0th element.
So there's probably not after all a connection to other unset
elements, but I think PWS's patch will alter the above behavior as
well?
