I guess you didn't read p. 51 of "Programming Ruby (2nd Ed)".  You can 
read the first edition online.  See the section Implementing Iterators 
here:

The behavior in question seems consistent with the way closures work in 
Ruby:

def func(x)
    y = 10
    lambda {puts x+y; y += 1}
end

p  = func(5)
p.call
p.call
p.call

--output:--
15
16
17

Is there something inconsistent with the way a block defined outside of 
any functions behaves versus a closure?
