   * Determine what sort of assigner should be used for the provided 'iter' (e.g. block).

   *
   * This method also has a second optimization which is to set 'noargblock' in the case that
   * the block is a block which accepts no arguments.  The primary reason for this second
   * optimization is that in the case of a yield with a RubyArray we will bypass some logic

   * secondary benefit is that a simple boolean seems to optimize by hotspot much faster
