Will it be possible to deduce, that the lifetime of that scoped value

   struct RefCounted(T)

     T t;
     scope ref T borrow() { return t; }
     alias this t;
   }

This enables RefCounted!T to be implicitly converted to a T, but with a
scoped result. This is a critical feature, one I spent a lot of time
thinking about, and hope it's right :-)

Hm... did you mean `alias this borrow`?
