I can see your point, but it depends on how used you are to 
reading chains of range algorithms. I read this as "given the 
integers 0 to 9, use them as the powers of ten and put them in an 
array". There is a point to be made that this is more 
self-documenting than the hand-written alternative: Here it is 
obvious that the ranks cover all powers of 10 from 0 to 9 in 
order. In the hand-written alternative you'd either assume that 
is the case, or have to meticulously count all the zero's to be 
sure.
