Better Example of Key/Value pair iteration

Based on my recent experience coming up to speed on manipulating objects, I'd suggest that the following example should be included somewhere in the API docs. Had I seen it ... would have saved me a lot of time and a lot of head scratching:

r({"a": 1, "b": 2}).do(
  (obj) =>  r.map(obj.keys(), obj.values(), (k, v) => [k, v]).coerceTo('OBJECT'))

I propose that this example be placed in the docs for map, because that's where I first went looking, trying to understand how I could iterate across all key/value pairs. Now, map does already have a tiny comment on this, but I missed it the first few times I looked, because my eye was drawn to the examples, and not the explanatory text.

Note: I personally find the following version harder to grok which is why I propose the version above:

r({"a": 1, "b": 2}).do(
  (obj) =>  obj.keys().map(obj.values(), (k, v) => [k, v]).coerceTo('OBJECT'))
