I was afraid that fully featured example was required for a serious
discussion. I guess we'll have to port some known example and get back
to you ;)

I was kind of hoping that some of the stuff we did were interesting
enough to discuss, such as:
 * using dsl model we have extended ubiquitous language from the
   backend to to database and frontends (most of PHP examples) for free
 * no impedance mismatch in relational database, while having very
   complex document like structures in the database, which helps with
   domain modeling and can be used for a lot of optimizations
 * model evolution - changes in the dsl cause automatic database
   migration, without the data-loss whenever possible (if scenario is
   implemented). Also, backend and frontend libraries are prepared for
   use without bugs and optimized
 * libraries instead of scaffolding - this is another major point which
   differentiates what we do from "standard" approaches to code
   "generation". Mixing generated and hand-written code is a big no-no.
