enum.each {...} Instance Public methods Iterates over the block according to how this Enumerable was constructed. If no block is given, returns self.

Enumerator.new(size = nil) { |yielder| ... }Enumerator.new(obj, method = :each, *args) Class Public methods Creates a new Enumerator object, which can be used as an Enumerable. In the first form, iteration is defined by the given block, in which a âyielderâ object, given as block parameter, can be used to yield a value by calling the yield method (aliased as +<<+): fib = Enumerator.new do |y| a = b = 1 loop do y << a a, b = b, a + b end end p fib.take(10

lzy.to_enum(method = :each, *args) â lazy_enumlzy.to_enum(method = :each, *args) {|*args| block} â lazy_enum Instance Public methods Similar to Kernel#to_enum, except it returns a lazy enumerator. This makes it easy to define Enumerable methods that will naturally remain lazy if called from a lazy enumerator. For example, continuing from the example in Kernel#to_enum: # See Kernel#to_enum for the definition of repeat r = 1..Float::INFINITY r.repeat(2).first(5) # =&g
