The example is not, of course, decisive--giving decimal notation a right-adjoining syntax, rather than left-adjoining, makes a compositional semantics readily available (7)--but it, and others like it, when combined (a) with the absence of a positive argument for the Modest Principle and (b) with the possibility, entertained by Szabo, that linguistic understanding is a matter of inducting from structurally similar cases (rather than deriving from constituent semantics), suffices to cast serious doubt on the Modest Principle, and hence on the role of the argument from understanding in motivating a principle of compositionality.
