The transformation that `#lang web-server` does to make serializable
continuations is very invasive, moving things around every-which-way.
I did not try to preserve using the apparent binding occurrence as the
actual binder, so the arrows are odd. I did a little experiments this
morning and couldn't find an easy way to fix the arrows. If someone
wanted to invest in this, I could point them in the right direction,
but I don't plan on spending much more time on it.
