I'm pretty sure that the submodule thing can be changed without any

explicitly, at least by texmacs and lilypond.
How do they use it?

Lilypond does:
--8<---------------cut here---------------start------------->8---
mod = scm_call_0 (maker);
scm_module_define (mod, ly_symbol2scm ("%module-public-interface"),
mod);
--8<---------------cut here---------------end--------------->8---
Solution: do something like:
--8<---------------cut here---------------start------------->8---
#ifdef HAVE_SCM_SET_MODULE_PUBLIC_INTERFACE_X
scm_set_module_public_interface_x (mod, mod);
#else
scm_module_define (mod, ly_symbol2scm ("%module-public-interface"),
mod);
#endif
--8<---------------cut here---------------end--------------->8---
(We just need to add that function.)
TeXmacs does:
<snip>
And we could add a ‘public-interface’ slot to ‘module-type’ and have
‘module-public-interface’ and ‘set-module-public-interface!’ refer to
it; for backward compatibility we’d also initialize the
‘%module-public-interface’ binding. How does it sound?
Actually the trick wouldn’t work in cases where the
‘%module-public-interface’ binding is mutated, as with Lilypond.
Given this and the above examples, I’d suggest dropping that binding
completely and sending patches to the Lilypond/TeXmacs people.

If you do add scm_set_module_public_interface_x, could you back-port it
to Guile V1.8.6 and V1.8.7?
Those are the lowest versions of Guile the upcoming stable release of
Lilypond will support.
