;; M-Eval input:
At this point you can start entering Scheme commands... but be prepared to wait
-a while for the result. After all, when evaluating commands in the MCE you are
+a while for each result. After all, when evaluating commands in the MCE you are
running a program in a Scheme interpreter running inside another Scheme
interpreter which is itself running on a Forth system that is implemented atop
-the Julia numerical computing environment. **That's three levels of
-abstraction more than a native Julia program experiences**, so some delay is to
-be expected!

For instance, the following example from SICP defines and demonstrates a
recursive list append procedure:
