+<p>Luan adds the block terminators <b>end_do</b>, <b>end_for</b>, <b>end_function</b>, <b>end_if</b>, and <b>end_while</b>.  These can be used to end the appropriate block type, but <b>end</b> can also be used to end any block.</p>

 <p>Most statements in Luan are the same as Lua.  Only those statements that differ will be listed here.</p>
