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.
