<span class="c"># Here be dragons, so a short explanation of the logic won&#39;t hurt:</span>
<span class="c"># We are trying to solve two problems: (1) access settings, in particular</span>
<span class="c"># settings.USE_I18N, as late as possible, so that modules can be imported</span>
<span class="c"># without having to first configure Django, and (2) if some other code creates</span>
<span class="c"># a reference to one of these functions, don&#39;t break that reference when we</span>
<span class="c"># replace the functions with their real counterparts (once we do access the</span>
<span class="c"># settings).</span>
