It's really interesting! :) I don't understand it, though :(

I've never understood what people meant by "virtual constructor"
anyway. The closest thing I can imagine is "clone() member function",
but that doesn't appear to be quite what you're doing.

Can this thing handle construction in raw memory, or does it always
do a dynamic allocation?
