The problem is that, whether retro() or dropBack() works with 
BidirectionalRange. So we need to find different solutions. If 
everything was an array, things would be easier, but I don't know 
how to get the last 4 elements of a range of known length, other 
than filtering! Does anyone have another practical solution?
