size: 20

new ['z',{i:6}]
size: 13

rename doc.x -> doc.z

old {o:{x:{p:0},z:{d:0}}}

old {o:{x:{p:0}, y:{l:{1:{d:0}}}}}
size: 43

new [['x',{p:0}],['y',1,{d:0}]]
size: 31

given {x:{y:5}}, capitalize x and y:

    x: {p: 0, o: {y: {p: 1}}},
    X: {d: 0, o: {Y: {d: 1}}}
}}

Convert the document {x:10,y:20,z:30} to an array [10,20,30]:

{ o: { x: { p: 0 }, y: { p: 1 }, z: { p: 2 } },
  p: null,
  di: [],
  l: { '0': { d: 0 }, '1': { d: 1 }, '2': { d: 2 } } }

  {r:{},i:[]},
  ['x',{p:0}],['y',{p:1}],['z',{p:2}],
  [0,{d:0}],[1,{d:1}],[2,{d:2}]
]

Rewrite the document {x:{y:{secret:"data"}}} as {y:{x:{secret:"data"}}}:

{ o: 
   { x: { p: null, o: { y: { p: 0 } } },
     y: { di: { x: {} }, o: { x: { d: 0 } } } } }
