OK, got it now. It doesn't actually address my problem above, but
you answered my question above anyway, and even made the environment
more flexible (that was the commit:

              Add #:env option to specify module for evaluating parser actions
              * module/nyacc/parse.scm (make-lalr-parser): add #env
                (make-lalr-parser/num , /sym) use (current-module) as default
              * test-suite/nyacc/lalr-01.test: add test case

so thanks a lot for that). I'm a happy camper :)
