Unable to install with GHC 8.6.5 cabal: 2.4.1.0 "Not in scope: data constructor `ClassA'" because of haskell-src-exts 1.22 update
Problem
Description of problem here.
- [x] I checked the issue tracker for existing issues about this problem.
- [x] I'm using the latest version of hindent.
I'm running Haskell Platform Core 8.6.5 x64 on Windows (ghc 8.6.5, cabal 2.4.1.0) and cabal install hindent fails to build Hindent (as well as v2-install). I've deleted irrelevant username for the log:
Microsoft Windows [Version 6.1.7601]

C:\Windows\system32>cabal install hindent
Warning: The install command is a part of the legacy v1 style of cabal usage.
Please switch to using either the new project style and the new-install
command or the legacy v1-install alias as new-style projects will become the
default in the next version of cabal-install. Please file a bug if you cannot
replicate a working v1- use case with the new-style commands.

This happens because hindent lists haskell-src-exts >= 1.20 as a dependency, but version 1.22 changed Asst and PAsst types (see https://github.com/haskell-suite/haskell-src-exts/pull/441) and even mentions the latter as a breaking change in CHANGELOG.
I'm not sure whether it's better to require exact haskell-src-exts version or to update hindent code.
Same here.
