It looks like while this works within a module, I haven't figured out
any workaround that allows the module to present the resulting generic
equal? to code that uses the module.

A re-export doesn't affect the module using the re-exporter, and export
and replace both fail with "Unbound variable: equal?", even though
there's a (define equal?  ...)  in the module.
