Hello,
I’ve noticed something really unexpected: take a Haskell package, say
‘ghc-libmpd’, build it several times (with --rounds or --check), and
notice that sometimes it will build successfully, and other times,
you’ll get a compiler error like this:
--8<---------------cut here---------------start------------->8---

That seems surreal to me.
Thoughts?

None of these are actual errors, but warnings. I’ve built a ton of
Haskell packages and never encountered transient errors.
