Using “super” in C++

Bjarne Stroustrup mentions in Design and Evolution of C++ that super as a keyword was considered by the ISO C++ Standards committee the first time C++ was standardized.

Dag Bruck proposed this extension, calling the base class “inherited.” The proposal mentioned the multiple inheritance issue, and would have flagged ambiguous uses. Even Stroustrup was convinced.

After discussion, Dag Bruck (yes, the same person making the proposal) wrote that the proposal was implementable, technically sound, and free of major flaws, and handled multiple inheritance. On the other hand, there wasn’t enough bang for the buck, and the committee should handle a thornier problem.

Michael Tiemann arrived late, and then showed that a typedef’ed super would work just fine, using the same technique that was asked about in this post.

So, no, this will probably never get standardized.

If you don’t have a copy, Design and Evolution is well worth the cover price. Used copies can be had for about $10.
