Hmm, why isn't CI running?

edit: for some reason this comment made "1 workflow awaiting approval" appear. it wasn't shown before. github being github i guess.

What should I do with the tell_env hint? The github backend also calls it like that, but it's inside a where there, which is fine for hlint

I don't know what happens.hlint is probably drunk. Add ignore to .hlint.yaml, I don't like "Use camelCase" hint anyway.

@fgaz what is the status of this PR?

[fgaz]

I've been using this branch for my personal projects. I don't remember too well what was the status of this but it looks like all comments are resolved. Let's rebase and see if tests still pass

[fgaz]

Hmm, I guess I'll need to update it to use ghcup since the ppa is no longer maintained

edit: by the way i see that travis is also still using the ppa even for ghc versions that aren't there
edit2: oh ok:

There is also legacy Travis-CI configuration generator, which is unmaintained.

Here you go, this should work
