Why not? Is that because of this thing you also wrote in the same
message: "use lists are allocated before the object"?

They are simply not currently built to be relocated.
attempts to do so will likely result in a huge mess.
my strong recommendation here would be to stop trying to go down this path,
Abe: I tried. :-(
and instead, if you want a sorted list,
just put them in a separate container and sort them.
Yup. I tried that. It went "boom". :-(
Maybe the essence what I did wrong when I tried it earlier was that the objects were
effectively on the stack. However, if/when using a typical implementation of either
"std::list" or "std::vector", only the container metadata should be on the stack [when the
container is a local], with the containees on the heap, no?
