Does using $ev in place of $_ in the last line of this snippet (in the real code) make any difference?

        my $ev = $_; #### You set $ev = $_ here
        if ($sometimes) { # sometimes goes this path and sometimes the
+ else
            eval {
                dave('proc2', {}, 'arg1', 'arg2');
                1;
            } or $log->warn("failed $@");
        } else {
            $log->logwarn("test $_"); #### But then use $_ here
