 No, you were right except for top-level method which are not really module
 functions

pigeon% cat aa.c
#include <ruby.h>

void Init_aa()
{
    rb_require("uu.rb");
    rb_funcall(rb_cObject, rb_intern("uu"), 0);
}

pigeon% cat uu.rb
def uu
   p "uu"
end

pigeon% ruby -raa -e 1
"uu"

 rb_cObject can access methods but not an instance variable defined (for
 example) in uu.rb
