Okay this approach started out nicely!

The C code boots both Guile and Clutter in the same thread(I think).

I can access the REPL port with nc. Thus, bliss and happiness so far!

However. Unevitable this happy narrative is disturbed by problems.

I am unable to export a C function to Guile. I've tried snarfing and a
more primitive approach as well. The C function doesn't wind up
available in the REPL. All I get is:

nc localhost 37146
...
(myloadfromdata "")
;;; socket:9:17: warning: possibly unbound variable `myloadfromdata'
socket:9:17: In procedure #<procedure b51600 at socket:9:17 ()>:
socket:9:17: In procedure module-lookup: Unbound variable: myloadfromdata


The only difference I can think of as compared to the documentation is
that inner main looks like this at the moment:

static void
inner_main (void *closure, int argc, char **argv)
{
     scm_c_define_gsubr ("myloadfromdata", 1, 0, 0, myloadfromdata);

  printf("starting guile server\n");

  scm_c_primitive_load("init.scm");
  printf("starting clutter\n");  
  main_view(argc, argv);
}

If I instead use        scm_shell (argc, argv); rather than
scm_c_primitive_load("init.scm"); the function is accessible,
so maybe there is some namespace issue?

init.scm looks like:
(define-module (mytest)
  #:use-module (system repl server))

(spawn-server)
