Scala - pattern matching with conditional statements?

Question

Is it possible to do something like:

def foo(x: Int): Boolean = {
    case x > 1 => true
    case x < 1 => false
}

Answer 1

def foo(x: Int): Boolean = 
    x match {
        case _ if x > 1 => true
        case _ if x < 1 => false
    }

Note that you don't have a case for x == 1 though...

Answer 2

I would write something like this:

def foo(x: Int) = if (x > 1) true
                  else if (x < 1) false
                  else throw new IllegalArgumentException("Got " + x)
