Re: Scala Object Notation ( SCON? )

Yes, but I don't like the fact of create a subclass of Person. I just
want to instantiate a Person. Suppose you have this Widget class:

class Widget{
  val name  = new Property("")
  val width = new Property(0)
  val height = new Property(0)
  val children  = new Property(Array[Widget]())
}

To populate the Widget properties without Object notation, you need to
write the next code

val w = new Widget
p.name() = "MyWidget"
p.height() = 10
p.children() = Array(
  label, panel,button
)

the previous code is not Property-Editor friendly, because the
"programmatic" nature. Then, a declarative syntax is the key. But
creating annonimous class is not declarative but programmatic, because
I would to assign a property 2 times:

new Widget{
  name="MyWidget"
  name="YourWidget"
}

In the other hand, I don't like to subclass Widget, because I just
want to instantiate Widget.
