Lennart, what is the next language DSL you are going to build? Prolog? XSLT?
Declarative 3D scene construction? ;-)
The ICFP programming contest in year 2000 was to write a ray tracer for a given declarative 3D scene construction language (CSG - constructive solid geometry). A team from Galois wrote a decent entry in Haskell, which did not win (those were the glory days of O'Caml), but it was placed in the top three. I believe with some careful googling, you should still be able to find a copy of the source code. I'm sure that if someone were to return to the idea now, the DSL for CSG could be improved in many ways, since the original language was simply given in the contest description, and there was no point in altering it.
