6.4.4 Structure matching

It is also possible to match against the fields of anonymous structures and instances:

    var myStructure = {
      name: "haxe",
      rating: "awesome"
    var value = switch(myStructure) {
      case { name: "haxe", rating: "poor" }:
        throw false;
      case { rating: "awesome", name: n }:
      case _:
        "no awesome language found";
    trace(value); // haxe

In the second case we bind the matched name field to identifier n if rating matches "awesome". Of course this structure could also be put into the Tree from the previous example to combine structure and enum matching.
