 Example from `class-wp-terms-list-table.php` :
 {{{
 $actions['view'] = '<a href="' . get_term_link( $tag ) . '">' . __( 'View'
 ) . '</a>';
 }}}
 What happens if `get_term_link` returns `WP_Error`, in this case?

 a) That part of the code, and all similar places should be fixed, I guess
 - to check for error before printing.
 b) A `WP_Error::__toString` method might help in some cases. It may return
 an empty string, or some string constant, or `WP_Error::get_error_message`
