I think the issue is that enabling -XTemplateHaskell clears the scope in some situations with recent versions of GHC. I'm looking into it.

I can confirm the first 4 failures.
The 5th seems to be a problem with ANSI coloring (added by stack?).

I think we can work around this in doctest by always enabling TemplateHaskell. We already do it if there are any prop> statements + doctest is already restricted to platforms that support TemplateHaskell (via ghci). So I hope this is safe to do.

I think it's still a bug. Specifically, it not only clears the scope but also unloads any modules that were specified on the command line. So if somebody puts :set -XTemplateHaskell into e.g. a setup chunk, he will still run into issues.

I filled an upstream bug here: https://gitlab.haskell.org/ghc/ghc/-/issues/20670

I think #312 will work.
