Ah, explained like that, it is indeed clear. Somehow, I was looking hard
for a continue, while you were providing a goto, ie. a more versatile tool.
Sorry for the confusion.
Some people regretted it needed an extra level of indentation, but
somehow it can be condensed to something like:
while cond do do :process_item:
-- code, code, code
-- some conditional
break :process_item:
-- code, code...
end end
Although the stutter might seem a little strange... :-)
