Hi @liyang !
Just found myself stumbling yet again over unexported constructors "issue" (a library had wrapped an STM primitive without a way to unwrap, breaking STM's composability I needed).
Here's a quick patch making the package compile with GHC 9.0.
cabal testpasses ✔️With 9.2 there's another issue, but for my case I found an alternative workaround.
Relatedly, did you see this hack?
importHiddenTH splice https://www.tweag.io/blog/2021-01-07-haskell-dark-arts-part-i/It'd be easy to roll out as an alternative library, but pity to see such a well-rounded package not supporting latest GHC's!
