Well,
if ($a) {
    $title = "bing";
} elsif ($b) {
    $title = "bang";
} else {
    $title = "bong";
}
is a considerable improvement :)

You can shorten it with,
$title = ("bing", "bang", "bong")[ $a ? 0 : $b ? 1 : 2]
but now no-one can understand it.

> my $title="bong";
> $title="bang" if $b;
> $title="bing" if $a;

is also more compact.  Most likely I'd use the
chained if/else with the layout shown, but that's
because I have a background in C, and no shoes. :D
