Ah, I understand. Currently in C++ you cannot inspect class members or call methods without a class definition (i.e. the class header file). For the most part, the C++ standard doesn&#x27;t really consider the object layout &quot;in scope&quot; so it&#x27;s unlikely we&#x27;ll see something like this standardized in the near future. This could change (maybe if&#x2F;when reflection is added?) but nothing like it is being talked about AFAIK.
