Tutorial D is an example language spec, but the syntax itself isn't really the point. D would overcome the object-relational mismatch by making the relational side much, much more powerful. It's really about unifying the ideas of "tables of data are relations" and "relations are logical propositions", so that one could have an über-powerful general purpose language that just happens to also be a natural interface for databases. D is essentially a set of low level prescriptions that the authors felt would be required in order to achieve such a language.
