So the setup is there is a value

foo: true

in the environment layer. Some modules need to share this data so they have class parameters such as

some_module::foo

that resolve the value with an interpolation function

some_module::foo: "%{lookup('foo')}"

It feels like it's not possible to do a

puppet lookup

locally from inside the module and have this work? It's possible to spec test because you can mock up the data, so there's that at least.
