digitalmars.D.learn - Returning the address of a reference return value in safe code -

reply Johan Engelen <j j.nl> writes:
This code compiles with 2.071, but not with 2.072 nor 2.073:
```
     struct S {
         int i;

         auto ref foo()  safe {
             return i;
         }

         auto bar()  safe {
             return &foo(); // <-- Error
         }
     }

     void main() {
         auto s = S();
         s.bar();
     }
```
The error is: "cannot take address of ref return of this.foo() in 
 safe function bar".

Is this a compiler regression, or is it a bug in the D code?

17117 and 17123 are already fixed on HEAD, no? So only two regressions remaining - I hope DIP1000 can be used to build new container libraries soon.

Maybe a bugfix in safety system? Should it go through deprecation process?
