right and you can generalize this idea even further

__comment_marker__ = $
__string_delimiter__ = [#, %]
$ also, even further
__comment_marker_keyword = #__my_own_comment_marker__%
__my_own_comment_marker__ = [&, *]
__assignment_symbol__ = <-
__attribute_delimiter__ <- -> & for attributes *
__call_delimiter__ = [!,@]
l = []
l->append!5@

you're a genius!!
