Convenience functions for working with tuples.

Tuple2

  • pairTo, double and swap for creating and arranging tuples
  • uncurry and apply for using functions with values in a tuple
  • maybeMapFirst and maybeMapSecond for lifting a Maybe out of a tuple

Tuple3

  • Copies and extensions of all Tuple functions to work with 3-tuples (first, second, third, mapFirst, mapSecond, mapThird, mapAllThree)
  • Functions for creating 3-tuples (join, joinTo, triple, splitFirst, splitSecond)
  • Functions for rearranging values in 3-tuples (reverse, rotateLeft, rotateRight, swapFirst, swapLast)
  • uncurry and apply for using functions with values in a 3-tuple
  • maybeMapFirst, maybeMapSecond and maybeMapThird for lifting a Maybe out of a 3-tuple
