Idea for Animate

gistfile1.js

// helper function
function animate( props, opts ) {
	var el = this,
		anim = $.Deferred(),
		propTimers = $.map( props, function( property, value ) {
			// $.Timer is a deferred(progress?? jQuery.Callbacks if they make it into 1.7)
			// object that is inserted into the jQuery.timers array that also
			// picks up some of the properties/calcs from jQuery.fx -- "step" function
			// animation data, etc...
			var prop = $.Timer( el, property, duration );
			// do some animation stuffs here!!!
			return prop;
		}).get();

	$.when.apply( $, propTimers )
		.done( function() {
			anim.resolveWith( el );
		}).fail( function() {
			anim.rejectWith( el );
		});

	// when "anim" is rejected, cancel all property animations
	anim.fail( function() {
		$.each( propTimers, function() {
			this.reject();
			// abort the timer if anything fails??
			// this doesn't happen in old code, but it could be done....
		});
	});

	return anim;
}

$.fn.animate = function( props, duration, easing, callback ) {
	// oversimplified:
	var opts = jQuery.speed(duration,easing,callback);

	this.queue(opts.queue, function( next ) {
		var el = $(this),
			anim = animate( props, opts );

		anim.then( next, function( clearQueue, gotoEnd ) {
			if ( clearQueue ) {
				el.queue(opts.queue).clear();
			} else {
				el.dequeue();
			}
			// gotoEnd would be handled in the $.Timer() reject
		});
	return this;
};
