New description:

 Since PHP 5.3, you have various ways of passing the same callback:

 {{{
 add_filter( 'the_content', array( 'My_Plugin_Main_Class', 'the_content' )
 );

 add_filter( 'the_content', 'My_Plugin_Main_Class::the_content' );

 add_filter( 'the_content', '\\My_Plugin_Main_Class::the_content' );
 }}}

 Currently, you have to use the exact same syntax in `remove_action()`, or
 it won't work.

 It would be nice if `_wp_filter_build_unique_id()` converted all these
 variations to a canonical representation.
