Subject: Re: pop/push, shift/unshift

Sorry for replying to my own post, can somebody confirm please that
the following code proves that Array#shift does not leak?
Thx in advance
def count
  i = 0
  ObjectSpace.each_object{ i += 1 }
  i
end

a = []
10.times do
  10_000.times do
    a << "a"
    a.shift
  end
  ObjectSpace.garbage_collect
  p count
end
