As a matter of fact there is a better way.

If you use an ENC, then you can return the role as a top scope
variable and your hiera configs can leverage those top scope

Here is an example where I've scrubbed any of our site data:

# puppet-enc ldap.example.com
  role::directory_server: null
environment: production
  context: production
  role: role::directory_server

The "classes" at the top and its "role" are for the classifying of the
ENC, but the "context" and "role" in the  "parameters" near the bottom
are variables that get exposed - hiera is one of the things that can
use those variables.

This works super slick for us.

For what it is worth, we also use a notion of context that allows our
ENC to describe whether a node is a "testing" or "production" type
system - we have hiera lookups based on that data, too.

Let me know if you want the hiera configs.
