So with that in mind, how about something like this (currently no
error checking):
(define-syntax re-export-public-interface
(syntax-rules ()
((_ mod ...)
(let ((iface (module-public-interface (current-module))))
(module-for-each
(lambda (sym val)
(module-add! iface sym val)
(hashq-set! (module-replacements iface) sym #t))
(resolve-interface 'mod))
...))))
