anonymous function could be an action

Great!

I had trouble with the anonymous callback function so I replaced it with a do_action(). My application is to bulk tag a custom post type with wp_set_post_terms( $id, $tag, 'foo-custom-taxonomy', true );

Putting that in an anonymous callback failed in some mysterious way.

I think it is easier and cleaner to change the plugin as follows (version 0.1.1):

Delete line 64: $func["callback"] = $callback;

Delete lines 146 – 159: if (version_compare(PHP_VERSION... else ... }

Add this line after the deleted line 159:
do_action( "seravo_custom_bulk_action_{$action}", $post_ids );

Then in you application, instead of specifying a callback in register_bulk_action(), add an action to your code:

add_action( "seravo_custom_bulk_action_{$action}", 'foo' );
function foo( $post_ids ) {
	// whatever you had in your anonymous callback
}

My foo is actually in class, so array( $this, 'foo' ). Maybe the class methods in my anonymous callback caused it to fail. Works now. And no PHP version checking is needed.
