Well the exact answer to your question is:
lookup("roles::${category}::${class}::classes", Array, 'unique').include()
However, the code you've shown is implementing a hierarchy for class
assignment duplicative of the Hiera hierarchy. Why not use Hiera's
hierarchy to your advantage?
hiera.yaml:
hierarchy:
- name: "Role data"
path: "roles/%{facts.category}.yaml"
Then have an array named classes, and just use
lookup('classes', Array, 'unique').include()
Much easier. Don't make your own hierarchy, make use of Hiera.
