Functional pearls are elegant, instructive examples of functional programming. They are supposed to be fun, and they teach important programming techniques and fundamental design principles. They traditionally appear in The Journal of Functional Programming, and at ICFP and affiliated workshops.

The history of functional pearls is covered by:

How to Write a Functional Pearl
Richard Bird. ICFP 2006.
Fifteen years of functional pearls
Richard Bird. ICFP 2006.
Strachey's functional pearl, forty years on
Mike Spivey, 2006.

There have been some 64 functional pearls in JFP, and some others at ICFP and the Haskell Workshop. There is also a collection of them in The Fun of Programming.

The pearls tend to concentrate on:

  • Examples of program calculation and proof
  • Neat presentations of new or old data structures
  • Interesting applications and techniques
