That explains the format change. While this seems a bit inconsistent
with the output of ${!array[@]}, I'm not going to quibble about format.
However, my comments concerned the reporting of nonexistent
indexes/keys. What's the purpose of the construct if it reports an array
index/key where none exists? To put it another way, before the change
the test:
[[ ${!array[$index]} ]]
was useful. Now, it's meaningless since it's always true -- even if
$index isn't an index of the array.
