Blocks in C and Objective-C are downright magical. They make coding easier
and potentially quicker, not to mention faster on the front end with multithreading
and Grand Central Dispatch. BlocksKit hopes to facilitate this kind of programming
by removing some of the annoying - and, in some cases, impeding - limits on
coding with blocks.
BlocksKit is a framework and static library for iOS 4.0+ and Mac OS X 10.6+.
