I like Clojure, but stopped using it due to not having a good way to define DTOs at a service level (I prefer noisy statically typed languages apparently). Best guess.

  (-> {}
    ice
    (rye :2-fingers)
    bitters
    absinthe
    shake
    strain
    garnish)

Now I think that strain flipped the returned type from drink to a glass with the drink.

All this shows is that OO and FP are duals [1]. I don't claim to get FP perfectly, but my moment of zen was realizing this.
