<div class="paragraph"><p>We have lots of ideas for projects to improve MLton, many of which we
do not have time to implement, or at least haven&#8217;t started on yet.
Here is a list of some of those improvements, ranging from the easy (1
week) to the difficult (several months).  If you have any interest in
working on one of these, or some other improvement to MLton not listed
here, please send mail to
<a href="mailto:MLton-devel@mlton.org"><span class="monospaced">MLton-devel@mlton.org</span></a>.</p></div>
