one counter-example : you !
If i give you a spec ( the source program ) i'm sure you are able to translate it to lots
of specific languages. And i'm pretty sure that beside some specific knowledge about each target language
you also have lots of general (design) knowledge you can apply for each translation.
The goal is to express it in lisp (through specific DSL). So it can be re-used.
