And in fact you can't even do:

    type JSON = Pipeline'Stage'Worker'Globl'Value'JSON

    case ... of
        JSON -> ...

Because you're giving an alias to the *type*, not the variant tag.
Haskell has a PatternSynonyms extension that I've not used heavily, but
Elm doesn't give you anything to work with here.
