The range returned by list isn't random access, and it can't be random access, 
so that won't work. Regardless, that would have given you the last element, 
not a range over just the last element. It would have to be list[$ - 1 .. $] 
to give you a range over just the last element, but that requires a sliceable 
random-access range (which DList's range can't be). If all you want is the 
last element, then use list[].back, since DList's range is bidirectional.
