I'd be curious to see experiments with variable numbers of line breaks to create additional structure. I find my own code significantly more readable by separating certain "sub-blocks" of code with two line breaks, with their internal structures having single line breaks.

  thing_1_a
  thing_1_b

  thing_1_c

  
  thing_2_a
  thing_2_b

It fits into the framework proposed here but is not mentioned specifically as having been investigated.
