<p>I was going to announce Nicholas Clark's progress on his <a
href="http://news.perlfoundation.org/2006/02/2006_q1_grant_votes.html#more">Improve
Perl 5</a> when I announced this quarter's grant votes. However, the summary below
(including the TODO information) isn't quite accurate. It was sent to me on May 11th,
and as of a May 20th email to me, I'm informed that even Nicholas' TODO items
have been accomplished, along with documentation of user pragmata. His grant appears to be finished and a great success. Many thanks Nicholas!</p>
<ul>
<li>The UTF-8 caching code is merged to 5.8.x</li>
<li>The constant folding changes are merged to 5.8.x, and have been adapted
to use the "flexible exceptions" system there.</li>
<li>Merijn and Nicholas have solved the Configure merge.</li>
<li>Making the lexical pragma implementation fully threadsafe turned out to
be opening a can of worms. It's done now.</li>
<li>The merge-able parts of the save_re_context code are now merged to
5.8.x. The structure on the save stack are duplicated by the threads clone
code.</li>
<li>The @INC source filter work has been done, and merged to 5.8.x</li>
<li>The pack "W" changes have been merged to 5.8.x (but not 'W' itself)</li>
<li>The code for magic and localisation has been checked, and merged to
5.8.x</li>
<li>I've audited all the code for UTF-8 and overloaded stringification bugs,
found and fixed quite a few.</li>
</ul>
<p>Todo:</p>
<ul>
<li>The work on taint, UTF-8 and TK hasn't been started yet.</li>
<li>The fixes for UTF-8 and overloading haven't been merged to 5.8.x yet.</li>
<li>The relocatable INC changes have not yet been merged to 5.8.x.</li>
<li>We're not sure how to handle packlists when everything is relocatable,
or even if a good solution solution exists.</li>
</ul>
