This is actually causing me some difficulty -- I'm implementing the R6RS composite library, which imports and then re-exports the bindings of a lot of the individual R6RS standard libraries. I'm running into a problem with `(rnrs syntax-case)', which exports `syntax-case'. Using the conventional set of module system introspection procedures (`module-ref', `module-variable', etc.), there's no way to see the syntax transformer and not the module -- to obtain the former, you need to use `nested-ref' (or some other workaround) instead. Any ideas? Regards, Julian
