Solution to nested-map-reduce-traversal challenge.
{- This is a solution to https://github.com/josevalim/nested-map-reduce-traversal
without using explicit accumulators.
You can run it with:
$ ghc Main.hs && ./Main
Which outputs:
Numbered 0 ("One",[Numbered 0 "A",Numbered 1 "B"])
Numbered 1 ("Two",[Numbered 2 "C",Numbered 3 "D",Numbered 4 "E"])
Numbered 2 ("Three",[Numbered 0 "F",Numbered 1 "G"])
