I should also point out that, since there is no way to actually find out whether anyone is using the `ref`-ness of the return type in the wild, the approach that you and Saurabh Das are taking really ought to include changing the symbol name and deprecating the old one.
Otherwise you could introduce subtle bugs into previously valid code; not every significant effect of removing `ref` will cause an error message at compile time *or* run time - some will just silently change the behaviour of the program, which is awful.
