Ah, I thought you used 'regular' casually. Apologies.

Yes, I am aware of the paper. In the "Summary" it says: "In this paper, we have
investigated several of the fundamental operations on built-in types in C++, and
identified characteristics they should have when applied to user-defined types."

In typical Russian style Stepanov pursues something he believes in with a vigor.
However, "built-in characteristics applied to user-defined types" is something I
seriously believe is mis-guided even though I understand the desire to simplify
and unify. It's unrealistic to expect complex user-defined types to fit in the
Procrustean bed of built-ins. IMO is should be the other way around... and I
believe that was the original C++ understanding (see Stroustrup "Evolution").
