Provides the ruby-1.9 block form of Enumerator, where you can write:
obj = Enumerator.new do |yielder| .. do stuff yielder.yield data # or: yielder << data .. etc end
When obj.each is called, the block is run once. It should call yielder.yield with each item it wishes to generate.
Example:
fib = Enumerator.new { |y| a = b = 1 loop { y << a a, b = b, a + b } } assert_equal [1, 1, 2, 3, 5, 8, 13, 21, 34, 55], fib.take(10)
