Then your best bet is probably to put in the mode's syntax-table the
syntax corresponding to the most common use of \ (either as an escape
char in strings or as an operator), and then use syntax-propertize to
put the other syntax on the other case (where you can check (nth
3 (syntax-ppss (math-beginning 0))) to see if you're within a string).
