+\section{Built-in Module \sectcode{operator}} % If implemented in C
+\bimodindex{spam}
+
+The \code{operator} module exports a set of functions implemented in C
+corresponding to the intrinsic operators of Python. For example,
+{}\code{operator.add(x, y)} is equivalent to the expression x+y. The
+function names are those used for special class methods; variants without
+leading and trailing '\_\_' are also provided for convenience.
+
+The \code{operator} module defines the following functions:
+
