-<p>A common task is to pair elements, with an initial or final element so the total length stays the same. This can also be done with a pairwise reduction, but another good way (and more performant without special support in the interpreter) is to add the element and then use windows matching the original length. Here both methods are used to invert <code><span class='Function'>+</span><span class='Modifier'>`</span></code>, which requires we take pairwise differences starting at initial value 0.</p>

+<p>A common task is to act on windows with an initial or final element so the total length stays the same. When using windows of length 2, the best way to accomplish this is with <a href="shift.html">shift functions</a> like <code><span class='Function'>«</span></code> or <code><span class='Function'>»</span></code>. If the window length is longer or variable, then a trick with Windows works better: add the elements, and then use windows matching the original length. Here we invert <code><span class='Function'>+</span><span class='Modifier'>`</span></code>, which requires we take pairwise differences starting at initial value 0.</p>
