Indeed it does.
That leads me to wander off topic. I had tried
$doc = "$doc";, which was close but does not work. Even this does not work:
my $copy = $doc;
undef *doc;
$doc = $copy;
After that,
$doc is still a blessed object (although
$copy isn't). From this, I conclude that I don't understand symbol tables. Why doesn't it work to
undef everything about
$doc? (For that matter, why isn't
$copy a blessed object?) Is there a way to "unbless"
$doc and to remove its object flag after it has been mucked with by XML::Writer?
