A variable reference produced by `(#%variable-reference)` can serve as the starting point for reflective operations on modules. Specifically, use
(variable-reference->module-path-index (#%variable-reference)) to get a reference to the enclosing module, and use `module-path-index-join` on that value and "../core/internat.rkt" to get a reference to the "../core/internat.rkt" module.
