Ansible 2.0.0-0.2.alpha2: roles and with_items?

Hello,

This being my first post on this mailing list, please tell me if I break
any custom.

I am trying to write a role that uses `with_items` along with `roles`.

However, I am currently stumbling upon a weird thing: I cannot use {{
item }} for role variable definitions.

Here is a MWE:

File vpnclients.yml

PS: Same issue with branch devel ; at a89412e ; with as only
modification the replacement of the header of ansible-playbook from
"#!/usr/bin/env python" to "#!/usr/bin/env python2".

Upping this message once, if I do nothing wrong I'll try filing an issue
on GitHub.
