Why do you call this a "domain specific language"?

Suppose you were the editor of a scientific journal and you wanted to
be able to allow people who only wrote in French to contribute to your
journal. How happy would you make them if you told them that they
could use their own language - provided - that the syntax and grammar
was the same as English?

What you wrote is not just lisp-like, it *is* Lisp.

Perhaps that is a clue that what you are actually doing is writing in Lisp? ;)

No. You are simply writing in Lisp.
