However I don't get the rules behind it, do you maybe want to add a warning case or open an issue for it on dscanner?

The rule is: return scope together means you can return pointers through this, and return without scope directly after it means you can return &this (or this by ref).

I don't know how dscanner is supposed to warn about this. You could implement limited escape checking in dscanner, but that simply checks what the compiler already checks with more accuracy.

@WebFreak001 Buildkite builds the latest tag v0.16.20, can you add a new tag so it sees this fix?
