It is also possible to further restrict patterns with the case ... if (condition): syntax:
var myArray = [7, 6]; var s = switch (myArray) { case [a, b] if (b > a): b + ">" + a; case [a, b]: b + "<=" + a; case _: "found something else"; } trace(s); // 6<=7
The first case has an additional guard condition if (b > a). It will only be selected if that condition holds, otherwise matching continues with the next case.
