Well, I have a book called "STL Tutorial and Reference Guide",
by David R. Musser and Atul Saini, which says on page xviii,
after mentioning Stepanov's work in Ada, "Another reason for turning to
C++, which Alex recognized early on, was that the C/C++ model of
computation, which allows very flexible access to storage (via pointers)
is crucial to achieving generality without losing efficiency."

It's not a direct quote from Stepanov, but I have some vague
recollection of Stepanov saying the same thing.  Sorry, I have
no cite.

As I said, such "flexible access" is also possible in Ada,
although it's somewhat more painful than in C++.
