+``QueryDict`` implements the all standard dictionary methods, because it's a
+subclass of dictionary. Exceptions are outlined here:
 
     * ``__getitem__(key)`` -- Returns the value for the given key. If the key
       has more than one value, ``__getitem__()`` returns the last value.
 
     * ``__setitem__(key, value)`` -- Sets the given key to ``[value]``

-    * ``__len__()``
-
     * ``get(key, default)`` -- Uses the same logic as ``__getitem__()`` above,
       with a hook for returning a default value if the key doesn't exist.
 
     * ``has_key(key)``
 
+    * ``setdefault(key, default)`` -- Just like the standard dictionary
+      ``setdefault()`` method, except it uses ``__setitem__`` internally.
+
+    * ``update(other_dict)`` -- Takes either a ``QueryDict`` or standard
+      dictionary. Just like the standard dictionary ``update()`` method, except
+      it *appends* to the current dictionary items rather than replacing them.
+      For example::
+
+          >>> q = QueryDict('a=1')
+          >>> q = q.copy() # to make it mutable

+          ['1', '2']
+          >>> q['a'] # returns the last
+          ['2']
+
     * ``items()`` -- Just like the standard dictionary ``items()`` method,
-      except this retains the order for values of duplicate keys, if any. For
-      example, if the original query string was ``"a=1&b=2&b=3"``, ``items()``
-      will return ``[("a", ["1"]), ("b", ["2", "3"])]``, where the order of
