23265	Canonical callback representation	scribu	nacin	"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.
