Very interesting -- thanks! The paper is Andrey Mokhov, Neil Mitchell,

Duh. I think I understand how this resolves now and I have a flat
structure, which I think works nicely:

Below is a short example showing that identifier-binding doesn't seem to
work quite right with Scribble's make-base-eval. It works fine with
make-evaluator from racket/sandbox.
I'm not sure why this is, but using syntax-local-value instead works
everywhere. (Implementation here:
The third argument to identifier-binding, top-level-symbol?, controls the
result of identifier-binding when the identifier is bound to a top-level
binding (and both the REPL and sandboxed evaluators are kinds of top-level
evaluation). The docs elaborate this way:
> The result is (list
identifier-binding returns #f for top-level bindings. I believe
make-base-eval is evaluating expressions at top-level.

What are *SL languages?

fwiw, I think here is a working version along the lines of your
original attempt.
