 to do it.

 This.

 I'm strongly in favor of using Composer for autoloading as the main
 argument against it seems to be that we should be taking baby steps.

 Using Composer just for autoloading for now seems to be the right baby
 step for me. It's not introducing any changes to WordPress its public API
 _and_ will work just for WP's core classes (what seems to be the goal
 here). It will also make things easier for real Composer support in the
 future (I dream of this day every single night).

 The following example composer.json file scans wp-includes/ and wp-admin/
 for classes and then dumps a PHP 5.2 compatible autoloader. It then copies
 the generated files to wp-includes/autoloader.


 {{{
 {
   "autoload": {
     "classmap": [
       "wp-includes/",
       "wp-admin/"
     ]
   },
   "require": {
     "php": ">=5.2.14",
     "xrstf/composer-php52": "1.*"
   },
   "scripts": {
     "post-install-cmd": [
       "xrstf\\Composer52\\Generator::onPostInstallCmd"
     ],
     "post-update-cmd": [
       "xrstf\\Composer52\\Generator::onPostInstallCmd"
     ],
     "post-autoload-dump": [
       "xrstf\\Composer52\\Generator::onPostInstallCmd",
       "rm -rf wp-includes/autoloader && cp -r vendor wp-
 includes/autoloader"
     ]
   }
 }
 }}}
