with_* vs *:

- name: make some directories
  file:
    type: directory
    dest: "/tmp/directory_{{ item }}"
  items:
    - a
    - b

will throw an error:

ERROR! conflicting action statements: file, items                                                                             

because it should be with_items:. It seems like a plausible typo and should be easy to detect that there's more than one key under a name: when the second key isn't one of the finite set of additional allowed toplevel keys {with_items, register, when, etc}.
