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`.
