Probably it doesn't matter at all. It's just some element that's
to be added to end of the currently iterated list.
It doesn't work that way, of course. I understood the question not
so much as about the "why", but rather about "how else can I achieve
such an effect".
for (x:list){Wouldn't that make the List grow until it hits OutOfMemoryError (OOME)?
.....; list.add(x);
}
(Isn't that the point of Andreas' response?)
No that wasn't it. I (boldly) assumed, that the ".....;" contained
something like: "if (x.exhausted()) continue; x.exhaustGradually();" :-)
Anyway, I meanwhile noticed, that my code is broken as well, because
I re-iterate also those elements that were originally in list...
