 Let's register a sidebar in functions.php and use digits for the value of
 the id key.

 {{{#!php
 <?php
 register_sidebar( array(
         'id'   => 'test123',
         // or 'id' => '123',
         // or 'id' => 123,
         'name' => 'test - Mega Menu',
 ) );
 }}}

 After that, the Widget is showing up at ''Appearance > Widgets''. But when
 we'd like to retrieve this widget using the dynamic_sidebar function, it
 won't work:

 {{{#!php
 <?php
 var_dump(dynamic_sidebar( 'test123' ));
 var_dump(dynamic_sidebar( '123' ));
 var_dump(dynamic_sidebar( 123 ));
 }}}

 All var_dumps will return ''bool(true)''
