- <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. -->
