--- Comment #2 from Dennis <dkorpel at live.nl> ---
I do like the idea of looking for adjacent `return scope`. 
I don't like the complexity behind rules a..e, I'd rather simplify it than add
on top of that, so how about an alternative proposal:

When adjacent keywords `return scope` are present, the result is `ref
returnScope`. Everything else results in `returnRef scope`. 

You can make returnRef member functions with `scope return`, no new grammar
needed. It also covers issue 20881.
