-Type-inference classes
-----------------------
-
-The CodeQL library for Python also supplies some classes for accessing the inferred types of values. The classes ``Value`` and ``ClassValue`` allow you to query the possible classes that an expression may have at runtime.
-
-Example
-^^^^^^^
-
-For example, which ``ClassValue``\ s are iterable can be determined using the query:
-
-**Find iterable "ClassValue"s**
-
-.. code-block:: ql
-
-   import python
-
-   from ClassValue cls
-   where cls.hasAttribute("__iter__")
-   select cls
