YASON: Yet another simple object notation

• Backwards compatible with JSON and JSONC

• Quotes on keys are optional if they only contain letters, digits, _, -, ., @, /

• Commas are optional

• Trailing commas are allowed

• Multiline strings:

  {
    test: | This is absolutely awesome!
            I love it!
    test2: |
      I love this, too!
  }

• ADT shorthands:

  {
    colors: [
      Rgb [0, 50, 30],
      "red",
      Hsl {
        hue: Deg 300,
        sat: 1,
        lum: 0.5,
      },
    ]
  }

  The above is equivalent to

  {
    "colors": [
      {
        "Rgb": [0, 50, 30]
      },
      "red",
      {
        "Hsl": {
          hue: { "Deg": 300 },
          sat: 1,
          lum: 0.5
        }
      }
    ]
  }

• Schema support

• Lisp-style syntax extensions

  (fn x y {
    foo: (case x
      is 3 => { bar: "baz" }
      is 4+ => (str "baz " x)
      is null => null
      else => +Rgb [(y), 50, 30]
    )
  })
