Wouldn't work in character alternatives without breaking compatibility. I've used both Perl's /x and Python's re.X in raw triple-quoted strings = extensively, and they are nowhere as nice as rx. Lisp-syntax languages really have an advantage here -- I wish I could = write an equally nice DSL in other languages. Some come close.
