i wasn't able to get that to work:
subclass.js:24: TypeError: Cannot call method 'call' of undefined
this._superConstructor_.call( this );
but this change works for me:
ChildClass.prototype._superConstructor_ = ParentClass;
ChildClass.prototype._superClass_ = ParentClass.prototype;
note the insertion of ".prototype".

Then i hacked it a bit...
Since MySubType already subclasses Object, we can change:
Object.prototype._extends_ = function( ChildClass, ParentClass )
{
if( 1 == arguments.length )
{
return this._extends_(this,ChildClass);
}
... same as before ...
}
And:
> Object._extends_( MySubType, MyType );
becomes:
MySubType._extends_(MyType);
otherwise _extends_ might as well be a non-member function.
Thanks for that tip! This will be useful!
