Real-world examples are mostly outdated

[sjakobi]

• lens is a good example
• Does Cabal still use haskell-ci? I didn't find a config at first glance.
• deepseq-generics has a Travis config which seems pretty useless – the latest commit didn't even get CI.
• filepath links to https://github.com/ghc/packages-filepath, but the active repo is https://github.com/haskell/filepath, which doesn't seem to use haskell-ci.
• arbtt doesn't seem to use haskell-ci
• circle-packing has an ancient .travis.yml, but the repo seems pretty dead.

Are there other examples that might even showcase some advanced configurations?

• aeson seems good – it even has some constraint-sets (constraint-sets are underdocumented #561).
• containers showcases the benchmarks and installed fields.

Any other good examples?
