If you write each of your modules as a .scm file which loads a C
library and calls an init function (see 1.6's srfi-13.scm, for
example), then you can just have two init functions in your C library,
one for the low-level functions, and one for the high-level functions,
i.e.

  ;; high-level.scm
  (define-module (high-level))
  (load-extension "libguile-foo-v-1" "scm_init_foo_high_level")
  (export bar)
  ...


  ;; high-level.scm
  (define-module (low-level))
  (load-extension "libguile-foo-v-1" "scm_init_foo_low_level")
  (export baz)
  ...
