Would someone please explain a little more about HI-14, though, and

fix that issue actually addresses it at all? The issue description is
about traversing structured data in
interpolation tokens, with an especial focus on structured fact values, but the
"fix" seems to have been to modify
the interpretation of /keys/. Either I'm misunderstanding something, or
that doesn't address the issue at all.
Kylo? Anybody? Bueller?
A key can be qualified and consist of several segments. Let's assume that the first segment is the key of some
structured data. The remaining segments of the key will then navigate in that data. Example:
$ hiera user
{"name"=>"kim", "home"=>"/home/kim"}
$ hiera user.name
kim
So the key user.name, when used as an interpolation token, will lookup 'kim'.
Also, see example under the "Qualified Key Lookup" here:
