Parser composability is trivial with Pratt parsers. One need only introduce the idea of denotation groups/categories, and allow one to specify a specific category along with a precedence. Add to this the ability to do ordered choice on denotations based on the first token(s) of the led/nud and you've got yourself a nice system :D
