+Many operations have an ``in-place'' version.  The following functions
+provide a more primitive access to in-place operators than the usual
+syntax does; for example, the statement \code{x += y} is equivalent to
+\code{x = operator.iadd(x, y)}.  Another way to put it is to say that
+\code{z = operator.iadd(x, y)} is equivalent to the compound statement
+\code{z = x; z += y}.

 The \module{operator} module also defines a few predicates to test the
 type of objects.  \note{Be careful not to misinterpret the
 results of these functions; only \function{isCallable()} has any
