Dict type

An immutable key-value data structure. Keys must be strings, and all the values have the same type: Dict["a" => 1, "b" => 2] is a Dict<Int>, and Dict[] is an empty dict.

Keys may be arbitrary expressions, such as Dict["x" ^ "y" => 1]. Dict items are evaluated in order, and the last value wins if there are duplicates.

Dict["a" => "hello", "a" => "world"]
//-> Dict["a" => "world"]

Dicts are values: set() and remove() return a new dict, and the original dict is unchanged.

let scores = Dict["Mario" => 10]
scores.set("Luigi", 8) //-> Dict["Luigi" => 8, "Mario" => 10]
scores //-> Dict["Mario" => 10]

struct Dict<T> {
  __BUILT_IN_IMPLEMENTATION: NoValue,
}
