<p>Can you see why?

<span class='spoiler'>
# /----------------- ww thinks problem is here ---------------\
<font color="#808080" class="htmlinserted">&lt;/span&gt;</font></span></p><p>Whilst I suspect that many people will jump on the use of each in a scalar context as the source of the problem, the actual cause is using <tt class='inlinecode'>%h</tt> as an rvalue.

</p><p>My (tentative) explanation is that not only is there only one iterator per hash, but that iterator is also used internally when a list is generated from a hash.

<font color="#808080" class="htmlignored">&lt;/span></font>
# ww thinks the end span should be  -----------^
#    though this <font ... /font> seems effectively a NoOp ???
