+Easy, isn't it?  You can also use <tt>InstIterator</tt>s to fill a
+worklist with its initial contents.  For example, if you wanted to
+initialize a worklist to contain all instructions in a
+<tt>Function</tt> F, all you would need to do is something like:
 
+<pre>
+std::set&lt;Instruction*&gt worklist;
+worklist.insert(inst_begin(F), inst_end(F));
+</pre>
 
+The STL set <tt>worklist</tt> would now contain all instructions in
+the <tt>Function</tt> pointed to by F.
