Subject: Re: [PHP-DEV] constructor hook
From: ralph@ralphschindler.com (Ralph Schindler)

This is one of the main use cases of AOP.  Demonstrated by this script:

     <?php

     class Bar {}
     class Foo {
         public function __construct(Bar $b) {
             echo 'instance of ' . get_class($b);
         }
     }

     function doDi($joinpoint) {
         // do smart stuff, then call:
         $joinpoint->setArguments(array(new Bar));
     }

     aop_add_before('Foo->__construct()', 'doDi');

     $f = new Foo; // 'instance of Bar'
