Calling Scala constructor with multiple argument lists

In Scala, I can create a method that takes more than one argument list:

def myMethod(value: Int)(fn: (Int) => Unit) {
  fn(value)
}

and call it like this:

myMethod(10) 开发者_如何学C{ value => println(value) }

How can I do the same thing with a class constructor? How do I call it?

This works.

scala> class MyClass(val value: Int)(val fn: Int => Unit)
defined class MyClass

scala> new MyClass(10)({value => println(value)})
