Well in a for loop, you only need one more index variable whereas here we store the whole index range.
Not the *whole* range, that would be impossible since it's infinite :) In this particular instance, index range is a struct consisting of three variables: initial state (0), current sequencer (n), and current element as cache. D ranges are lazy. Well, most of them.
