so basically I *just *need to loop over extra variables in an inline way
to construct the unique name and the unique policy template, then, the
usual loop for the module will create the resources in aws.
- should using *Lookup *a good start for inline loop ?
- as *nested *and *subelements *can't seem to achieve this, what other
solution I can explore ?
cheers
