(is it still even a goal for the strawman to compile on 2.12...?)

Indeed, I didn’t check that… We have additional type annotations in other tests to make them compile with 2.12. I’m really looking forward to remove them ASAP (see #113).

I don’t think we should try to support 2.12.

I have dropped this repo from the 2.12 community build
