Hmm... forgive me, I havent been keeping up with Lua development... instead
of labels, could we have 'levels' of break?  For example, if you have a
nested for loop in, say, C, and you break out of the inner one, you are
still in the outer one, and there is no way of knowing you broke out of the
inner one unless you set some kinda weird flag... I think something like
'break 2' would be really useful... and of course have a simple 'break' be
synonymous with 'break 1'.

Just my $.02
