+<p>LLVM IR allows you to specify name aliases for certain types.  This can make
+it easier to read the IR and make the IR more condensed (particularly when
+recursive types are involved).  An example of a name specification is:
+</p>
+
+<div class="doc_code">
+<pre>
+%mytype = type { %mytype*, i32 }
+</pre>
+</div>
+
+<p>You may give a name to any <a href="#typesystem">type</a> except "<a 
+href="t_void">void</a>".  Type name aliases may be used anywhere a type is
+expected with the syntax "%mytype".</p>
+
+<p>Note that type names are aliases for the structural type that they indicate,
+and that you can therefore specify multiple names for the same type.  This often
+leads to confusing behavior when dumping out a .ll file.  Since LLVM IR uses
+structural typing, the name is not part of the type.  When printing out LLVM IR,
+the printer will pick <em>one name</em> to render all types of a particular
+shape.  This means that if you have code where two different source types end up
+having the same LLVM type, that the dumper will sometimes print the "wrong" or
+unexpected type.  This is an important design point and isn't going to
+change.</p>
