Subject: How To Keep a Block on a Recursive Function

Hi. I have a recursive function (it calls itself) that accepts a block.

  def arecursor(param)
    [...]
    yield var
    [...]
    if (some condition)
      arecursor(another_var)
    end
    [...]
  end

When the function is first called, the yield statement succeeds. But
after the function calls itself, it looses the block. How do I make the
block persistant-- can I do something like this::?

      arecursor(another_var) { use my block }

Thanks,
Oliver
