This prevents the evaluator from running an analysis pass beforehand.
It would also prevent syntax expansion from happening beforehand, I
think.

As an example, Chez Scheme, if it uses the interpreter, actually runs
the cp0 pass (like our peval) before passing code off to the
interpreter.

It is an interesting thought experiment, yes ;-)
