Haskell anagram generator

A simple anagram generator, inspired by the original solution our Haskell team wrote for the April 2015 West London Hack Night challenge.

Example usage:

cabal run "west london hack night"

Example output:

snoot thegnland whick
...
sloth tendon whacking
...
slat thonged whinnock
...
shocking the townland
