I agree. Ada does not need records with external-to-record tags. (What the heck would we call these, btw? Untagged tagged records? Tagged untagged records?) In a more general case, what Ada needs slightly more that is vaguely on a similar topic is satisfying Steelman requirement 3-3F, one of the very few Steelman requirements that Ada83 didn't live up to: https://www.dwheeler.com/steelman/steeltab.htm#3-3F Presumably the external-to-record tag could be such a constant field of the record, where that field does not occupy storage in the record, as 3-3F requires permitting. (But Steelman 3-3F does nothing to rectify my fear that the compiler would choose the wrong strong type and thus choose the wrong external-to-record tag in certain situations, importing C++ slicing into Ada.)
