I did not miss it. See my reply to Timon.

Yes it is dated, as modern languages abandoned multiple pointer types based on 
that experience.

The only one I even know about is Microsoft Managed C++, where they have gc and 
nogc pointers. What a disaster. Nobody wants to write code in Managed C++. That 
scheme never made it into Standard C++.

A feature needs to be useful and easy to use in order to get people to use it.
