  <ul>
    <li><code>mkstr</code>: concatenates its symbols and returns the printable representation
 of the result</li>
+   <li><code>symb</code>: passes its arguments to <code>mkstr</code>
+   to produce a printable representation, and returns the symbol built
+   from this result; if the symbol does not exist, it will be
+   created.</li>
+   <li><code>group</code>: takes a list as input and produces a
+   list of sublists of length n.</li>
+   <li><code>flatten</code>: Returns a list of all atoms present in
+   the provided list.</li>
+   <li><code>compose</code>: allows a number of functions with the same arity
+   to be composed together in a chain.</li>
   </ul>
 
+ <h3>Let Over Lambda</h3>
+
+ <ul>
+   <li><code>defmacro!</code>: provides automatic gensyms and
+   once-only evaluation. Arguments that begin with g! will be
+   automatically <code>gensym</code>'d, and arguments that begin with
+   o! will only be evaluated once. Inside the body, the o! arguments
+   should be called as their equivalent g! argument: o!x should be
+   called in the body as g!x.

+
+ <h3>hash-table functions</h3>
+ <ul>
+   <li><code>sethash</code>: convenience function for setting a value
+   in a hash table.</li>
+   <li><code>hashkeys</code>: returns a list of all the keys in a hash
+   table.</li>
+   <li><code>hash-table-to-alist</code>: converts the hash table to an
+   alist of <code>(key . value)</code> pairs.</li>
+   <li><code>alist-to-hash-table</code>: converts an alist to a hash
+   table.</li>
+   <li><code>enable-hash-table-reader</code>: Enables the reader
+   macro <code>#{}#</code> for hash tables. The resulting hash-table
+   will use #'equal for equality. For example,
+
+<pre>
+#{:a :b :c :d}#
+</pre>
+
+will create a hash-table with the keys <code>:a</code>
+and <code>:c</code>. <code>:a</code> stores the value <code>:b</code>,
+and <code>:c</code> stores the value <code>:d</code>.</li>
