A:
You should define your type in a module, and then compile it:
module Test where
data FooBar = Foo | Bar
By invoking ghc -c foo_bar.hs, the object file foo_bar.o will be generated without having to define main.

@aXqd Wrong hint, sorry. I've updated my answer. I've tested it locally, and it works; the object file will be generated.
