Try formatting the haskell code (see issue details)

https://github.com/tweag/ormolu
- (https://github.com/lspitzner/brittany)
- (https://github.com/ennocramer/floskell)

NOTE: please coordinate with any other in-progress branches to avoid painful merge conflicts

The issue names no files, tests, or entry points. Compare the linked ormolu, brittany, and floskell projects first, then review the repository's existing Haskell sources and coordinate with in-progress branches. Done would require an agreed formatting approach and consistently formatted Haskell code without creating merge conflicts.
