It should maybe be called in an init_* function rather than
a syms_of_* function: the difference is that syms_of_* functions are
called only once, before dumping, whereas the init_* functions are
re-executed every time Emacs is started (i.e. before and after the

But calling it from Fload_module is probably fine as well (and maybe
even better).
