  # Pipeline we run on each PR. Slightly different from the pipeline we run when
  # stuff get merged into `master`. In this setup, we do want a quick feedback, and
  # we therefore parallelize as much as we can using many different jobs. We also
  # avoid options like `--coverage` or `--haddock` on each build since those take
  # needless time.
