They could not be implemented on top of the existing arc-to-scheme translator, because that's what it is: an arc-to-scheme translator, not an interpreter. Scheme doesn't have first-class environments, so we can't shove them into arc without writing a full-fledged arc interpreter.

I've had a closer look at Arc2.tar. You're right. I thought that runtime environments were handled explicitly.
