Some logical markup.
Combine function pairs: add() and __add__() go together. This way they
share a single description and use less space.

+The \module{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 \code{x+y}. The
function names are those used for special class methods; variants without
leading and trailing \samp{__} are also provided for convenience.
