Yes, I recall this now. It's usefule with continuations. But it stills
seems odd, considering,

  irb(main):001:0> s = proc { x }
  => #<Proc:0xb7b366a4@(irb):1>
  irb(main):002:0> x = 1
  => 1
  irb(main):003:0> s.call
  NameError: undefined local variable or method `x' for main:Object
        from (irb):1
        from (irb):1:in `call'
        from (irb):3

So I suspect it has something to do with paralled assignment?
