what is the use case for this? FYI the filter was created to act like the dict lookup.

[rwanyoike]

@bcoca a happy misuse of dict2items:

A workflow to turn:

foobar:
  boss: /tmp/su99
  noop: /tmp/3311

into a to_json ready list:

- file: boss
  path: /tmp/su99
- file: noop
  path: /tmp/3311

would require extra step(s) to remap the key/value from dict2items's output:

{{ dict | dict2items }}

... it comes so close.

make that the example and also note 'version added' in docs
