Comment:
You could use a wrapper class:
{{{
class My_Functor {
function __construct( $cb, $args ) {
$this->cb = $cb;
$this->args = $args;
}
function invoke() {
$args = func_get_args();
return call_user_func_array( $this->cb, array_merge( $args,
$this->args ) );
}
}
$extra_args = array( 'value1', 'value2', 'value3' );
add_action( 'some_hook', array( new My_Functor( 'my_callback', $extra_args
), 'invoke' ) );
}}}
This way, we can keep add_action() blazing fast for the normal case.
