First, here's a piece of working code that prints the values "1 2 3" as one would expect:

class Array
  def each2
    each {|value| puts value}
  end
end
[1, 2, 3].each2

**HOW IN THE NAME OF ALAN TURING DOES _each2_ PASS _value_ TO _each_***?!?!
--------------

It doesn't. each2 is passing {|value| puts value} to each. The declaration of each is *like*:

def each(&block)
  ...iteration block...
    block.call(item)
  ...end iteration...
end

Values are passed to blocks with either "yield item" or "block.call(item)".
