The usefulness of this depends on how you want to solve the problem at hand. One approach to programming is to create a DSL for the problem domain and then solve the problem using that DSL. Languages (such as Common Lisp) that include advanced means of metaprogramming are perfect from this perspective. Otherwise, one has to create an API to approximate the DSL - which could be rather hairy, so one may try to manage the complexity of this particular representation by either using a preprocessor or even, as an extreme measure, by writing a separate language processor (compiler or interpreter) for the DSL.
