alias :old_initialize :initialize
# Provides the ruby-1.9 block form of Enumerator, where you can write:
#
# obj = Enumerator.new do |yielder|
# # ...
# yielder.yield(data) # or: yielder << data
# # ...
# 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
# }
# }
#
# fib.take(10) #=> [1, 1, 2, 3, 5, 8, 13, 21, 34, 55]
#
