<li>
There are some planned <b>structural improvements</b> to the compiler,
like compressed snapshot maps or generic handling of calls to helper
methods. These are of lesser importance, unless other developments
elevate their priority.

<li>
<b>Documentation</b> about the <b>internals</b> of LuaJIT is still sorely
missing. Although the source code is included and is IMHO well
commented, many basic design decisions are in need of an explanation.
