The case for Scala

An alternative implementation

David,

I really like your code. I've got an alternative implementation that demonstrates a slightly different take on Scala:

def interpret(in: String, f: String => Unit) {

def sing(n: Int): List[String] = {
def bb(in: Int) = in match {
case 1 => "1 bottle of beer"
case x => ""+x+" bottles of beer"
}

if (n == 0) Nil
else {
f(bb(n)+" on the wall.")
f(bb(n)+".")
f("Take one down, pass it around,")
f(bb(n - 1)+" on the wall.")
sing(n - 1)
}
}

in.map(Character.toUpperCase).
foldLeft(0) {
case (x, 'H') => f("Hello World") ; x
case (x, 'Q') => f(in) ; x
case (x, '9') => sing(99) ; x
case (x, '+') => x + 1
case (x, _) => x
}
}

interpret(argv(0), println)

I hope the readers like to see the flexibility and different styles in Scala code.

Thanks,

David
