I'm not talking about a library solution.

That's how you get scoped, deterministic destruction of class 
objects in the pure language.

That's different. That's what I meant by `scope class`, but 
`scope Object` is referring to it as a storage class

https://dlang.org/deprecate.html#scope%20as%20a%20type%20constraint

"scope as a storage class attributed to variables, function 
parameters, etc. is not deprecated."

But this is why it is complicated: as the class author, you can't 
know how it will be used. The same is also true of structs, which 
the next part of the blog will talk about. So you need to take 
some appropriate care.

It can be done right though.
