It seems that the tricky part is that the hide() function (as in all
animation functions) use a setInterval, but return the "this" object
immediately.
Ohhh. I have an idea.
What if the wait() function set a flag in the object saying this object is
waiting for an animation to finish.
Then, any subsequent jQuery.fn methods that are called get added to a queue
to be executed after the animation is finished.
Once the animation is done, the wait flag is turned off and jQuery.fn
methods are executed immediately as usual.
So it would look like this:
jQuery("div").hide("slow")
.wait()
.addClass("done")
.find("span")
.addClass("done")
.end()
.show("slow")
.wait()
.removeClass("done")
.find("span")
.removeClass("done");

First, you can do that with the callback parameter.
jQuery("div").hide("slow")
.wait()
.addClass("done")
.find("span")
.addClass("done")
.end()
.show("slow", function() {
$(this).removeClass("done");
})
But to create a wait() function, I think you have to create a lock/
semaphore (a simple counter), incremented in jQuery.anime (or anything
that create a timer callback?), decremented at the end of the anime,
and tested in the wait() function.
