This compiles, but should it?
I think the @safe attribute is not significant here, because that code is
wrong, in unsafe code too.
I think DMD lets it pass because it's not able to spot the bug. I don't know if
and when it will be able to trace such situations, but in the meantime:

I would say the possibility of a bug makes this code unsafe by
definition. Ref returns must be considered unsafe by default, unless the
compiler can know for sure that the object will exist beyond the
lifetime of the function.
