+ * ext/objspace/objspace.c: add ObjectSpace#reachable_objects_from.
+ This method returns an array of objects referenced by given object.
+ If given object is special objects such as true/false/nil/Fixnum etc
+ then it returns nil. See rdoc for details.
+ [ruby-core:39772]
+
+ * test/objspace/test_objspace.rb: add a test for this method.
+
+ * gc.c: add rb_objspace_reachable_objects_from().
+ To make this function, add several member `mark_func_data'
+ to rb_objspace_t. If mark_func_data is not null, then
+ gc_mark() calls mark_func_data::mark_func.
+
+ * gc.h: export rb_objspace_reachable_objects_from().
