method with angle brackets (<>)

Question

Is it possible to have angle brackets in method names , e.g. :

class Foo(ind1:Int,ind2:Int){...}
var v = new Foo(1,2)
v(1) = 3 //updates ind1
v<1> = 4 //up         


        

Answer 1

With a little trickery you can actually get quite close to what you want.

object Foo {
  val a:Array[Int] = new Array(100)
  def <(i:Int) = new Updater(a, i)
}

class Updater(a:Array[Int], i:Int) {
  def update(x:Int) {
    a(i) = x
  }
  def >() = this
}

Foo<1>() = 123

I am not sure why Scala requires the () though. And yes, this is a bit of a hack...
