Unfortunately not yet. My compiler project has stagnated a bit, though I still work on it occasionally (most recently I've now come to the point where I have to implement GC - the compiler racks up 2GB of mostly garbage while trying to compile itself...). I do want to eventually retarget it to SDE, but it's unlikely to happen this year...

Did you ever get around to exploring SDE's in a Ruby context?
