Comment (by dave1010):

 I've updated the summary to include PSR-4 now, not that it makes a lot of
 difference.

 Would the API that plugins used to get hold of the autoloader look
 something like this?

 {{{
 $GLOBALS['wp_autoloader']->addNamespace('Acme', __DIR__ . '/src');
 }}}


 Without trying to derail this ticket, it would be worth considering making
 it easier to integrate with composer in the long term.
 http://wpackagist.org/ already exists and seems to be very popular (but
 obviously can't be used in all cases).

 It would be great if plugins could have a simple file (e.g.
 `autoload.json`, in the same format as the `autoload` section in
 `composer.json`) that WordPress picked up automatically.
