Your question is not what you really want to ask about.

You don't want to exit the block. You want to exit the loop that is 
inside the each method. And you break out from loops using break.

Just exiting the block would be useless, because you would still be 
inside the loop, and the each would just go on to the next iteration. In 
fact, you exit the block each time control gets to the end of the block 
normally, but then the block is called again in the next iteration.
