Important note there. This did not work for me at first, because I was
being a dodo-head (technical term) and had:
$sth = $dbh->prepare("select * from" . $foo->method .
"order by date_time desc");
Note lack of spaces before and after $foo->method, which causes things
to break. Languages that care about whitespace irritate me!

Well the answer was, as usual, to RTFM before spending an hour trying to
figure it out. And, the corollary to that is, if something appears
amazingly complicated, and you're working with Perl, you are clearly
thinking about it wrong. Easy things easy, hard things possible. I just
get so wrapped up in trying to solve things like this that I waste
entire afternoons on it, which really aggravates me.
