You're missing the point. Some programming languages (Lisp family in particular) allow you to build DSLs directly, with the tools the language itself provides.
And then, inside this "DSL" in Lisp, can you have a completely different
language, with significant spaces and unmatched parentheses? Or is it just
Lisp data structures that are then interpreted and you're pretending to
use language other than Lisp because of its flexible data structures notation?
