This is why the topic is called "*(Almost)* everything...". In general 
case we may not include this case with label-statement into proposal, 
since the construction you wrote isn't practice IMO. But, we should 
consider also theoretical things and this case it can be better to avoid 
the case at all then to solve it -- especially if there is no much 
profit in practice from it. Though, if we can manage it, why not?
