At least some objections that make sense and I'd love to see in 
the very first announcement. If you see any issues that prevent 
treating "const scope int" as "const scope ref int", please tell 
about them and they will be addressed in DIP. Because it is the 
intention. I don't understand what aliasing are you speaking 
about.
