AFAIK, Perl's GC collects variables as soon as their reference
counter goes down to 0.

In my opinion, this is little surprise the first time you see it,
but good feature in the long term. And after all, since you lost
the last reference to $window, you won't be able to destroy or
hide this window forever.. and that is not what I consider a good
programming feature.

But anyway if all people are against that, of course..
