But this can be achieved easier, as e.g. (0..9).cycle already returns an 
Enumerator.

ruby-1.9.2-p136 :002 > foo = (0..9).cycle
  => #<Enumerator: 0..9:cycle>
ruby-1.9.2-p136 :003 > foo.next
  => 0
ruby-1.9.2-p136 :004 > foo.take 12
  => [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 1]
ruby-1.9.2-p136 :005 > foo.next
  => 1
ruby-1.9.2-p136 :006 >
