It iterates over its items and calls <font face="Menlo" class="">debugDescription </font>on them. I found it a bit unexpected thus my question here. Is it desired behavior? I would expect <font face="Menlo" class="">description</font> and <font face="Menlo" class="">debugDescription</font> call respective methods on the contents.</div><div class=""><br class=""></div><div class="">(I asked the same question in the PR but thought it’s general, so might be worth posting here)</div></body></html>
