| 16 | <p id="label-sequences-views">A <em>view</em> is a sequence adaptor delivering an altered presentation of | |
| 17 | one or more underlying sequences. Views are lazy, meaning that their | |
| 18 | elements are only computed on demand. Similarly to the short-circuit | |
| 19 | <a class="reference internal" href="./logical-operations.html">logical operations</a> and <a class="reference internal" href="./eval-if.html">eval_if</a>, views make it possible to avoid | |
| 20 | premature errors and inefficiencies from computations whose results | |
| 21 | will never be used. When approached with views in mind, many | |
| 22 | algorithmic problems can be solved in a simpler, more conceptually | |
| 23 | precise, more expressive way.</p> | |
