The other way to do it would be something like:
- name: Create mysql servers
mysql_user: name=app host="{{
hostvars[item]['ansible_eth0']['ipv4']['address'] if
hostvars[item]['ansible_eth0'] is defined else item }}"
with_items:
- localhost
- 127.0.0.1
- "{{ groups['webservers'] }}
The above example should work with 1.5, although I do believe that is over
complicated, hard to read and not easily understand.
You could expand that to a regular {% if ... %}{{ address }}{% else %}{{ item
}}{% endif %} type line, but that gets even longer and harder to read in my
opinion with all of the special characters that get mixed into that line.

I see, thanks. I'd still be interested if there's any other way to do it, as it
would be useful elsewhere too and prefer not to duplicate plays if possible.

I would split your create user into 2 tasks. 1 for localhost and the other for
web servers:
- name: Create localhost mysql users
mysql_user: name=app host="{{ item }}"
with_items:
- localhost

- name: Create webservers mysql users
mysql_user: name=app host="{{
hostvars[item]['ansible_eth0']['ipv4']['address'] }}"
with_items: groups['webservers']

# - <here I want to list ip numbers of the webservers group>
How can I make the list include IP numbers of each webserver host. I know I can
use ansible_eth0.ipv4.address to map from hostname to IP, but I don't know how
to map a whole list to another list. And I can't see any way to define a
variable as the result of a loop.
