 In a [http://hardcorewp.com/2012/enabling-action-and-filter-hook-removal-
 from-class-based-wordpress-plugins/#comment-494 comment] made by someone
 on a recent blog post of mine entitled ''"Enabling Action and Filter Hook
 Removal from Class-based WordPress Plugins"'' the commenter lamented on
 the complexity of removing hooks when plugin developers use classes.

 Plugin developers who use classes use so many different architectures;
 i.e. some use static methods, others using instance methods with
 singletons, other's use class factories, etc. If WordPress were to allow
 plugin developers to filter the `$function` value passed to the
 `_wp_filter_build_unique_id()` function then our plugins could mask much
 of the complexity required for the site builder to interact with our
 plugins. I could for example support the following syntax even though I'm
 really might be using a Singleton:

 {{{
 remove_action( 'the_content', 'My_Plugin_Main_Class::the_content' );
 }}}

 Of even the following so the site builder doesn't have to know all about
 my class hierarchy:
 {{{
 remove_action( 'the_content', 'My_Plugin::the_content' );
 }}}

 Then it would just be up to the plugin developer to add some simple
 documentation to their plugin's README file.
