Possible Misunderstanding

Hi!

Thanks very much for your submission to Ansible. It sincerely means a lot to us.

We believe the ticket you have filed is being somewhat misunderstood, as one thing works a little differently than stated.

This is on purpose, as you are allowed to use the vars_prompt to set a variable used in hosts:, for example:

- hosts: "{{ myhost|default('localhost') }}"
  vars_prompt:
    - name: myhost
  gather_facts: False
  tasks:
     - debug: var=inventory_hostname

In the future, this might be a topic more well suited for the user list, which you can also post here if you'd like some more help with the above.
