def unshift!(view_or_constant, style=nil, opts = {}, &block)
      opts[:raw_block] = block if block
      unshift(view_or_constant, style, opts).get
    end
def unshift!(view_or_constant, style=nil, opts = {}, &block)
      opts[:raw_block] = block if block
      unshift(view_or_constant, style, opts).get
    end
Same as prepend, but instantly returns the view, without having to use .get

 @example
   @my_button = rmq.prepend! UIButton
   @my_label = rmq.prepend!(UILabel, :my_label)
