I don't understand: `parse-partial-sexp' uses the syntax-table to
identify start and end sequences of comments and strings.  Sometimes
syntax-table text-properties are used.  What kind of "variables" do you
have in mind?

You know about previous comments and strings iff you are neither in a
comment nor in a string.  Strings and comments can be nested in so many
forms that it's strongly encouraged to either use the state returned by
a previous call of `parse-partial-sexp' or assure that you start outside
of any comments or strings.  `syntax-begin-function' if provided is a
good choice here.
