Comment (by goldfire):

 Let's not debate `VisDepATM` now. That's something I've pondered for a
 while, but I think it matters in coercions more than types. You're right
 that it won't affect printing.

 I quite like putting the `@` on kinds with `-fprint-explicit-kinds`.
 Regardless of anything else, we should absolutely do this. I wouldn't have
 it interact with `-dsuppress-type-applications`.
