and then ask for the evaluation of:
- (+ 2 (three-thunk))
+ (+ (+ 2 (three-thunk)) 1)
you'll see something like:
<blockquote>
-<strong>"hi"</strong> 5
+<strong>"hi"</strong> 6
</blockquote>
-So the demonstration we tried in class was pedagogically flawed. It didn't properly display how continuations are a minimally effective apparatus for representing affective meaning. In fact, continuations were still doing the work, but it wasn't the explicit continuations we were writing out for you. It was instead continuations implicit in the `print` operation.
+In other words, the printing of "hi" already happens on the side, outside of the main evaluation. Continuations don't need to be explicitly invoked.

So a better demonstration would do without any device like `print` that already incorporates continuations implicitly. Any continuation-manipulation should be fully explicit.
