+> An attempt at a review (although note that I don't have commit access,
+> so my opinion is not final):
+>
+> Should `calendar_autocreate_commit` really default to 1? I would personally
+> expect that any new features that synthesize new pages should not commit
+> them by default - I'd prefer to avoid cluttering git history with generated
+> pages. (Indeed, should the option even exist?)
+>
+> I'd personally do the conditional in gencalendaryear more like:
+>
+> [[!format perl """
+return unless $config{calendar_autocreate};
+"""]]
+>
+> to reduce the indentation depth of the more interesting code.
+>
+> The recursion to generate missing years:
+>
+> [[!format perl """
+if (not exists $wikistate{calendar}{minyear}) {
+        $wikistate{calendar}{minyear} = $year;
+} elsif ($wikistate{calendar}{minyear} > $year) {
+        gencalendaryear($year + 1);
+        $wikistate{calendar}{minyear} -= 1;

+> does seem to be correct on closer examination, but it took me a while

+> * generate 2005
+>   * recurse to generate 2006
+>     * recurse to generate 2007
+>       * recurse to generate 2008
+>         * recurse to generate 2009
+>           * recurse to try to generate 2010 (no effect)
+>         * minyear = minyear - 1 = 2010 - 1 = 2009
+>       * minyear = minyear - 1 = 2009 - 1 = 2008
+>     * minyear = minyear - 1 = 2008 - 1 = 2007
+>   * minyear = minyear - 1 = 2007 - 1 = 2006
+> * minyear = minyear - 1 = 2006 - 1 = 2005

+> I think it might be clearer (as well as less
+> recursion-happy) to use iteration:
+>
+> * generate 2005
+>   * recurse to generate 2006
+>   * ...
+>   * recurse to generate 2009
+> * minyear = 2005
