ansible >= 2.0 complains: Using bare variables is deprecated

[gretel]

TASK [os-hardening : delete rhosts-files from system | DTAG SEC Req 3.21-4 dest=~{{ item }}/.rhosts, state=absent] ***
task path: /Users/me/dev/roles.galaxy/os-hardening/tasks/rhosts.yml:7
[DEPRECATION WARNING]: Using bare variables is deprecated. Update your
playbooks so that the environment value uses the full variable syntax
('{{users.stdout_lines}}').
This feature will be removed in a future release.
Deprecation warnings can be disabled by setting deprecation_warnings=False in
ansible.cfg.

usually, the variables need to be enclosed ({{ }}) to be safe. regards
