Description
e.g. groupBy ((==)onfst) $ sortBy (compareonfst) should be replaced with groupSortOn. Perhaps have an "hlint" test that only runs if hlint is on the PATH, so I have it fixed locally, but the buildbots don't need to compile hlint?

Research direction
Start by locating how HLint defines and tests custom rules, then inspect how the groupBy/sortBy example could be represented as a suggestion. Check how an optional hlint test could be run only when hlint is on PATH without requiring buildbots to compile it. Done means the proposed rule and optional test approach are defined and covered by the relevant test setup.
