 The union and intersection of sets can be computed with the
! \method{union()} and \method{intersection()} methods or
! alternatively using the bitwise operators \code{\&} and \code{|}.
 Mutable sets also have in-place versions of these methods,
 \method{union_update()} and \method{intersection_update()}.

 It's also possible to take the symmetric difference of two sets. This
 is the set of all elements in the union that aren't in the
! intersection. An alternative way of expressing the symmetric
! difference is that it contains all elements that are in exactly one
 set. Again, there's an alternative notation (\code{\^}), and an
 in-place version with the ungainly name

 Without such an encoding declaration, the default encoding used is
! 7-bit ASCII. Executing or importing modules containing string
! literals with 8-bit characters and no encoding declaration will result
 in a \exception{DeprecationWarning} being signalled by Python 2.3; in
 2.4 this will be a syntax error.

 The three major operating systems used today are Microsoft Windows,
 Apple's Macintosh OS, and the various \UNIX\ derivatives. A minor
! irritation is that these three platforms all use different characters
 to mark the ends of lines in text files. \UNIX\ uses the linefeed
! (ASCII character 10), while MacOS uses the carriage return (ASCII
! character 13), and Windows uses a two-character sequence containing a
 carriage return plus a newline.

 As usual, there were a bunch of other improvements and bugfixes
 scattered throughout the source tree. A search through the CVS change

 Python 2.2 and 2.3. Both figures are likely to be underestimates.
