6.4.8 Match on multiple values

Array syntax can be used to match on multiple values:

var s = switch [1, false, "foo"] {
    case [1, false, "bar"]: "0";
    case [_, true, _]: "1";
    case [_, false, _]: "2";
  }
trace(s); // 2

This is quite similar to usual array matching, but there are differences:

• The number of elements is fixed, so patterns of different array length will not be accepted.
• It is not possible to capture the switch value in a variable, i.e. case x is not allowed (case _ still is).
