Description

A reminder to myself to come back and clean these up. For example:

  • unwordsWith is Data.List.intercalate
  • makePairs is zip
  • pair is uncurry
  • isLeft, isRight are already in Data.Either

Research direction
Examine the file Utils.hs in the repository to identify functions that duplicate standard Prelude or Data.List functions. For example, replace unwordsWith with Data.List.intercalate, makePairs with zip, pair with uncurry, and isLeft/isRight with Data.Either.isLeft/isRight. Ensure appropriate imports are added and existing usage is updated. The issue provides initial examples; check for any other similar reimplementations.
