I've implemented experimental and rudimentary support in [Resyntax](http://docs.racket-lang.org/resyntax) for custom `#lang`s, including non-s-expression `#lang`s. This allows a language to configure Resyntax's default suggestions on code written in that language, and gives Resyntax the ability to perform automated refactoring over files written in that language.

I'm looking for testers who have created their own `#lang` and have code written in it that they'd like to refactor in a manner that can be reasonably automated. If you've written a `#lang` that fits this description, and you're down to try something wacky, let me know and let's see if we can make it happen.
