This is quite interesting.  :)

I just did a little more research, and these three calls all return
the same interface, but the last one doesn't work with Guile 1.9:

  guile> (resolve-interface '(guile))
  #<interface (guile) 7f3f91117840>
  guile> (module-public-interface the-root-module)
  #<interface (guile) 7f3f91117840>
  guile> (module-public-interface the-scm-module)
  #<interface (guile) 7f3f91117840>
  guile>

So, it looks like we might want to do this:

-      SCM scm_module = ly_lily_module_constant ("the-scm-module");
+      SCM scm_module = ly_lily_module_constant ("the-root-module");


Thanks,
Patrick
