Is there a way that doesn't require the named variable?
$_ and return  given big_calculation();

or:

given big_calculation() {
        return when true;
}
Don't those return C<undef>, as opposed to the value of C<$_>?  I.E. 
wouldn't it be:

    $_ and return $_ given big_calculation();
-or-
    given big_calculation() {
        return $_ when true;
    }
