Kill as soon as possible the special case handling of tuples in foreach

I'm all for unpacking consistently, but to reach consistency you 
first have to break something, the iteration on arrays or the 
iteration on ranges of tuples. The first is documented and it's 
present since D1, the second is recent and undocumented and it 
causes evolution troubles for D toward possible implementations 
of tuples. What do you want to kill? I prefer to kill the second, 
and do it yesterday.
