Each day is done in a different language:

• Day 1: Standard ML (impl, description)
• Day 2: Factor (impl, description
• Day 3: Racket (impl, description)
• Day 4: Ruby (impl, description)
• Day 5: Go (impl, description)
• Day 6: C (impl, description)
• Day 7: Prolog (impl, description)
• Day 8: Haskell (impl, description)
• Day 9: Erlang (impl, description))
• Day 10: C++ (impl, description)
• Day 11: Common Lisp (impl, description)
• Day 12: Rust (impl, description)
• Day 13: Python (impl, description))
• Day 14: Java (impl, description)
• Day 15: JavaScript (impl, description)
• Day 16: Pyret (website) and OCaml (impl), description)

• Day 18: Elixir (impl, description)
• Day 19: Mercury (impl, description))
• Day 20: Clojure (impl, description)
• Day 21: Lua (impl, description)

Let's see if I can keep it up!

TODOs

• Ideally, blog a bit about this project and the languages.
• Ensure we use stdin/file input wherever possible, rather than hard code the puzzle inputs.
• More idiomatic refactors of many of the later ones, not just "You can code Scheme in any language."
