   2 A *view* is a sequence adaptor delivering an altered presentation of
   3 one or more underlying sequences. Views are lazy, meaning that their
   4 elements are only computed on demand. Similarly to the short-circuit
   5 |logical operations| and |eval_if|, views make it possible to avoid
   6 premature errors and inefficiencies from computations whose results
   7 will never be used. When approached with views in mind, many
   8 algorithmic problems can be solved in a simpler, more conceptually
   9 precise, more expressive way.
