It's not an "antipattern", not in Lisp at least. It is a way to improve maintainability dramatically. Probably, the only sane way to do so. But, of course, you have to do it the right way. eDSLs must be designed as chains of trivial, flat transforms, so you can easily understand each stage and inspect any state of transformation at any moment. Most of the Racket users, unfortunately, lack this discipline, and in general are practicing a suboptimal approach to metaprogramming.
