Yesss. Nice. A bit of Escher here:
Imagine an instance of eval evaluating an instance of eval that
evaluates the first instance.

And then think about what happens if you try to evaluate anything else
than those evals in any of those evals, not forgetting that you're
working inside an eval and getting evaluated yourself.

The grandfather paradox is peanuts compared to that.
