+**********************
+Concrete Objects Layer
+**********************
+
+The functions in this chapter are specific to certain Python object types.
+Passing them an object of the wrong type is not a good idea; if you receive an
+object from a Python program and you are not sure that it has the right type,
+you must perform a type check first; for example, to check that an object is a
+dictionary, use :c:func:`PyDict_Check`.  The chapter is structured like the
+"family tree" of Python object types.
+
+.. warning::
+
+   While the functions described in this chapter carefully check the type of the
+   objects which are passed in, many of them do not check for *NULL* being passed
+   instead of a valid object.  Allowing *NULL* to be passed in can cause memory
+   access violations and immediate termination of the interpreter.

+Generic operations on sequence objects were discussed in the previous chapter;
+this section deals with the specific kinds of sequence objects that are
+intrinsic to the Python language.
