Can someone confirm or deny that this is deprecated in 1.9?

Not just the specific case above, but the general functionality that
block parameters can be instance variables, setting the instance
variable as a side-effect of just invoking the block. For example:

  p @a
  #=> nil

  3.times{ |@a| }

  p @a
  #=> 2

  p VERSION
  #=> "1.8.5"
