A sealed object is an instance of any class that wasn't declared with
the 'dynamic' attribute. Most classes, such as Button, are non-dynamic.
This means that if you try to access a property that wasn't declared at
compile time, you'll get a runtime error. For example, if you do
var b:Button = new Button();
b["foo"] = 1;
you'll get an RTE because the Button class didn't declare a property
named 'foo' at compile time and wasn't declared to be dynamic.
But if you do
var o:Object = new Object();
o["foo"] = 1;
you'll create a new 'foo' property on o. This is allowed because the
Object class was declared to be dynamic.
You declare a class to be dynamic like this:
public dynamic class MyClass extends SomeOtherClass
{
}
