Compare these two situations:
class SuperClass
{
private var list:Array;
public function SuperClass()
{
list = new Array();
}
}
class SubClass extends SuperClass
{
// when instantiated, the list variable is automatically initialized
}
This is as it should be. The
the constructer gets invoked automatically (and its the only function which
does all other overrides this is not the case for) but the super class's
constructer is being called without arguments so whats happening on a code
level is this
super();

Hi,
when the superclass has a default contructor without parameters, there is no
need to call it explicitly.
I'd like to turn it around though, no matter what or how you have defined
them, always call them explicitly for clarity's sake and self documentation.

quirk?
Nope, not a language

Interesting thread, Alan!
What is ECMA Specification saying to that situation?

slightly OT, but I have noticed some time ago, that Flash IDE claims
the super() call to be the first line in the constructor of the
extending class. But I noticed to the same time, that when compiling
