Comment(by martinlagardette@…):

 After inspection in the code, the dev is using `RCLASS` to determine
 wether or not an object is an instance of `NArray`:
 {{{
 #!c
 static void
  na_check_class_narray(VALUE v)
 {
   if (TYPE(v) != T_CLASS) {
     rb_raise(rb_eRuntimeError, "class required");
   }
   while (v) {
     if (v == cNArray || RCLASS(v)->m_tbl == RCLASS(cNArray)->m_tbl)
       return;
     v = RCLASS_SUPER(v);
   }
   rb_raise(rb_eRuntimeError, "need NArray or its subclass");
 }
 }}}

 We do not use `m_tbl`, so this cannot be emulated :-(.

 I am looking for a solution right now. We do have an equivalent of what is
 being done, but it is totally different and would require ugly `#ifdef
 MACRUBY` etc. Instead we'd rather find a solution that can be used with
 ruby and macruby :-)
