  Monads

  📚 Finally, monads! Still could use more documentation, but they're here and they work 😄

  [1, 2, 3] \>\>\> fn x -\> [x + 1] \>\>\> fn y -\> [y \* x, y \* 10, x - 1] endend#=\> [2, 20, 0, 6, 30, 1, 12, 40, 2][1, 2, 3]\>\>\> fn x -\> [x + 1] end\>\>\> fn y -\> [y \* 10, y - 1] end#=\> [20, 1, 30, 2, 40, 3]
  

  Of course they work on things other than lists. I'll will be moving the ADT-specifc implementations to Algae, so if you want Maybe, Either, and friends, please use it in conjunction with that library.

  Major Reorganization

  Still a bunch more to do, but this is already much better. Merging to master, and will continue to tighten stuff up and work through the roadmap.

• v0.3.0 Changes

  January 12, 2016

  Applicative Functors are here!

  Things to note:

  • wrap (i.e.: pure) & apply are here!
    • Operator for apply: <<~ and ~>>
    • Reversed operator arrow direction for consistence with Elixir
    • ie: in Haskell we think about applyping "over" things (apply [(+1)] [1,2,3])
    • In Elixir, we're piping thing into the application ([1,2,3] ~>> [&(&1 + 1)])
    • Can still write in the Haskell order, with reversed operators:
      • Haskell: (\x y -> x + y) <$> [1,2,3] <*> [4,5,6]
      • Elixir: &(&1 + &2) <~ [1,2,3] <<~ [4,5,6]
  • Have to exclude Kernel.apply for modules
    • In the future, we will either need to create a use, or rename apply (probably the later)

• v0.2.0 Changes

  November 08, 2015

  Functor protocol, functions, and spot-check helpers

  • Only the covariant functor, more varieties will follow

• v0.1.0 Changes

  October 29, 2015

  First draft of the Monoid protocol
