We have this at work, actually. I wrote a macro language for pascal in guile. At first it was a first draft, but it worked well enough and got to stay. It generates enormous amounts of code that would otherwise have been unmaintainable. As it is now, it is just a couple of hundreds of lines of scheme and pascal code that recursively generates pascal. We had some problems making it scale (as I said, it generates a lot of code), but the upcoming 2.2 guile solved most of our issues, and I rewrote parts of it to make it fast enough. Got it down from 1 minute to 10 seconds on a 10+ minute build when rebuilding everything. I might be able to opensource it. With minor tweaks, it can probably be made a bit more language-agnostic.
