Inline jQuery(function(){}) and jQuery.ready queue to enable async loading of jQuery. It also queues jQuery.noConflict.
Include jquery-stub.js before inline code that uses jQuery.
When using $async you can use jquery-stub-async.js to simply hook into the jQuery dependency or other dependencies.
You could use fn.toString() and a regular expression to selectively set the dependencies.
$async.js({
src: '', // to save size, $async does not verify src and fails when omitted.
inline: callback_name + '();',
dependencies: 'jquery',
exec_timing: 'requestIdleCallback'
});
