--- Comment #1 from RazvanN <razvan.nitu1305 at gmail.com> ---
I guess the error may make sense. `t` is a struct and is going to get destroyed
when `errorize` finishes execution. Since `t._error` is a reference type, a
reference to `_error` is going to be escaped and then `t` is going to get
destroyed and you end up with a reference to some destructed data. I am not
advocating that the error should be issued, just saying that it could make
sense.

What is puzzling is that if you return `t._error` or if you comment the call to
`kind()` in the in contract then the error goes away. Also, there is no
-dip1000 or @safe involved so I don't know why the compiler is such a nagger.
