I'm not sure about it. It seems that in guile, null? checks for an empty
list, and nil is used for lisp compatibility.

I wouldn't like to use null for this issue, because the component name
is not a list.

The piece of code doing that kind of work seems to be:
  if (SCM_NFALSEP(scm_eq_p(scm_comp_name, SCM_NIL))) {
    return SCM_BOOL_F;
  }
SCM_NIL doesn't exist. Anyone knows a way to do it?

Regards,

Carlos
