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?

Yeah, this is another regression caused by DIP1000.

Christ.

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?
