That doesn’t compose in a class hierarchy, though.

That's a good point... You might be able to work around that using a template function factory e.g. `make_foobar<ChildrenFooBar>()`. I'm not sure what's a good pattern here, I don't write much C++.

As long as the every element of the hierarchy is noexcept-movable it still composes. It is just very cumbersome.
