`else` / `if`

Sometimes you see even more bizarre examples:

        Subject: Retrieving an Entry Within a File
        Message-Id: <MPG.139f24a68ea4317f989682@News.CIS.DFN.DE>

        if ($device eq $_) {

        $mail{To} = 'pager@domain.com'; } else { 
        if ($device ne $_) {$mail{To} = 'email@domain.com'; }

The previous slide says this should be:

        if ($device eq $_) {
          $mail{To} = 'pager@domain.com'; 
        } elsif ($device ne $_) {
          $mail{To} = 'email@domain.com'; 
        }

But really it should be:

        if ($device eq $_) {
          $mail{To} = 'pager@domain.com'; 
        } else {
          $mail{To} = 'email@domain.com'; 
        }

Exercise: Would it be better to write

        $mail{To} = ($device eq $_) ? 'pager@domain.com'
                                    : 'email@domain.com';

        $mail{To} = ($device eq $_ ? 'pager' : 'email') 
                    . '@domain.com';

else / if
