Oh! Right, thank you. I forgot to rewrite this. I'd like to keep the
details about why "tricking the compiler to be quiet" should not be
done. One of my fears about removing uninitialized_var() is that folks
may start adding open-coded versions to silence warnings. I'd like to
keep a section in deprecated.rst that describes the problem and why
those kinds of work-arounds should not be used.
