Ada could allow T'Class for untagged T. T'Class would be an indefinite
type with values consisting of the actual type's tag and its value. When
T is by-value type, you pass T'Class to a subprogram as tag + value.
When T is by-reference type, you pass tag + reference.
Upon dispatch, you strip the tag from the value or reference before
passing value/reference down.
P.S. No re-dispatch is possible in this model, sorry.
P.P.S. Tagged type is a special case when T and T'Class have same
representation.
