The idea of `scope` is allowing `@safe` access to raw 
pointers/arrays with limited lifetime. RAII in C++ doesn't do 
anything to protect basic types like that.

What are you thinking of? If `return scope` and `return ref` used 
symbols such as `^%` and `^$` (for example), that wouldn't make 
it simpler.
