I apologize if I don't fully understand your question, but it sounds
like what you want is an array of Symbol'Class.  But that's not allowed
-- Ada wants all array elements to be of the same size.  So what you
need to do is have an array of Symbol_Ptr, where type Symbol_Ptr is
access all Symbol'Class.

I don't really see how the generic-ness in your example makes any
difference to this point -- maybe I'm missing the point.
