BTW :the changes and advances made in Sage since the last edition of
this book may warrant a revision, possibly a new edition. If only for
the installation procedures (Conda installation, WSL on Windows, Github
replacing Trac, etc...) and the interfaces (Jupyter replacing the Sage
notebook, emacs as an alternative to command line, etc...).
Yes, for sure... It would be great. We just need manpower, time, and so
on :-)

Indeed, I found on page 43 the example:
sage: 123 + \
....: 345
468
which does not work presently. The first mention of "\" as an
operator is on page 162, where it's given as a shorthand for
solve_right in a table (with "/" as a shorthand of solve_left)
It also occurs on p168 (sect. 8.2.2) [twice] , p281, p283 (with
explanation), p302 (in a summary table). Even in the sections where
it is used, `\` is used much more often as a line continuation .
As far as the book is concerned, I think certainly fixing "\" to
work as line continuation is definitely more important for its
correctness, since that's used in much more places in the book (and
also in all the chapters where `\` is used as an operator). In all
the places except the summary table on p302, I saw the alternative
solve_right spelling explicitly mentioned. So impact of deprecating
the notation is rather limited. You could just add it to an
errata/updates list.
