So I wrote a 99% compatable query-language compiler. It is ugly, and itself slower than it should really be, but it beats the pants off the interpreter. It runs undre CScheme version 5.3; I suspect it would take non-trivial but doable effort to port it to a different scheme. In case anyone else is in the same position, I'd be happy to send other instructors the code, on a completely and utterly as-is basis. -------
