> Thanks. I still don't understand where the bits live that tell you which type T is for a given node.
Yup. You'd have to set that up yourself. It could be anywhere. It could be in a separate array, it could be in the previous node-data, etc.
you wouldn't put it in the Node (capital N) datastructure though, that is privileged.
Personally, I would say doing something like this is "bad idea bears" unless you are absolutely certain you need it and you should explore using, say, data payload type with a union field instead, if possible (though know that that comes with a potential memory penalty)
