If you take that message in context, you'll find that a professor of computer science is here asking how one would implement a meta-circular evaluator <URL:http://en.wikipedia.org/wiki/Meta-circular_evaluator> for Guile after local-eval has been thrown away. You answer by giving an example of how to use Guile as the implementation language for a non-meta non-circular evaluator instead. You could likely also use Guile for _bootstrapping_ a meta circular evaluator. But that is not really the same thing. -- David Kastrup
