+The most general solution is arguably a bit of a hack. Due to Python's
 afformentioned behavior concerning evaluating default arguments to functions
 (see :ref:`default_args`), you can create a closure that binds immediately to
 its arguments by using a default arg like so:
 
 .. code-block:: python
 
-    def create_adders():
+    def create_multipliers():
         return [lambda x, i=i : i * x for i in range(5)]

 situations. Looping to create unique functions is unfortunately a case where
 they can cause hiccups.
