Modern regexp engines allow you to use an arbitrary char as the pattern
delimiter. If I've got slashes in my patterns, I tend to use # as the
delimiter, which allows you to avoid Leaning Toothpick Syndrome. Other people
may use | . # is visually distinctive and not as common as / in some
string-replace contexts, though:
perl -p -i -e 's#"$line"#"$newline"#' file
