Why would you want a common abstraction for asynchrony? Well, compare these two. Might've gone a bit overboard, but the code was so easy with tasks I didn't realize what I was heading into when I was writing the callback hell version... Note: This would've been just as succinct using MAFuture or ReactiveCocoa or whatever. The important part is h…

	// callback hell
	- (void)fetch:(NSURL)url saveWithCompletion:(void(^)())myCompletion errorHandler:(void(^)(NSError))errorHandler
	{
	[downloader fetchURL:url completion:^(NSData *data) {
	[parser parse:data completion:^(NSDictionary parsed, NSError err) {
	if(parsed) {
	[database save:completion^{
	if(myCompletion)
	myCompletion();
	}];

Both "about to register" and "registered" are printed, and shortly after Springboard crashes :( This is the entirety of the source in this dylib.
