| <p id="label-algorithms-iteration-algorithms">Iteration algorithms are the basic building blocks behind many of the |
| MPL's algorithms, and are usually the first place to look at when |
| starting to build a new one. Abstracting away the details of sequence |
| iteration and employing various optimizations such as recursion |
| unrolling, they provide significant advantages over a hand-coded |
| approach.</p> |
| <!-- Of all of iteration algorithms, ``iter_fold_if`` is the |
| most complex and at the same time the most fundamental. The rest of |
| the algorithms from the category |- -| ``iter_fold``, ``reverse_iter_fold``, |
| ``fold``, and ``reverse_fold`` |- -| simply provide a more high-level |
| (and more restricted) interface to the core ``iter_fold_if`` |
| functionality [#performace]_. |
| |
| .. [#performace] That's not to say that they are *implemented* |
| through ``iter_fold_if`` |- -| they are often not, in particular |
| because the restricted functionality allows for more |
| optimizations. --> |
