It's a bit non-conventional, but the switch block can be used like so:
switch(true) {
case (x < y):
dosomething();
break;
case (y == 0):
dosomethingelse();
break;
default:
somethingelseentirely();
break;
}
...this way, your case statements can be expressions themselves, and it
will always pick at least one of them to fire.
