ssl ssl Parameters to a block may be existing local variables; if so, the new value of the variable will be retained after the block completes. This may lead to unexpected behavior, but there is also a performance gain to be had by using variables that already exist.[For more information on this and other ``gotchas,'' see the list beginning on page 127; more performance information begins on page 128.] A block may also return a value to the method. The value of the last expression evaluated in the block is passed back to the method as the value of the yield.

ssl This is how the find method used by class Array works.[The find method is actually defined in module Enumerable, which is mixed into class Array.] Its implementation would look something like the following. class Array   def find     for i in 0..

ssl .size       value = self[i]       return value if yield(value)     end     return nil   end end [1, 3, 5, 7, 9].find {|v| v*v > 30 } » 7 This passes successive elements of the array to the associated block. If the block returns true, the method returns the corresponding element. If no element matches, the method returns nil.

ssl The example shows the benefit of this approach to iterators. The Array class does what it does best, accessing array elements, leaving the application code to concentrate on its particular requirement (in this case, finding an entry that meets some mathematical criteria). Some iterators are common to many types of Ruby collections. We've looked at find already. Two others are each and collect.
