The problem is that the code we write doesn't deal directly

where `scope` on the left applies to the `this` pointer or the

Kagamin just told me I needed to use `return` instead of
`scope` to get things to work and I'm still not sure why.
The way I think about it is if you have a function that takes a
pointer, any pointer, and either returns it or a pointer
derived from it (dereferencing or indexing) that argument must
be marked `return`. In your case it was a pointer derived from
`this` so `return` must be applied to `this`.
I guess my problem is that DIP1000 talks about returning scope
values and they don't seem to actually exist in the
implementation.
