Henry,
I think you can use
var ip:LzView = (this.immediateparent cast LzView);
I had forgotten that Tucker put this in recently, and should solve the
issue! It's different from 'as' in that 'cast' will throw an exception
if the conversion is not possible. So no big need for 'as'.
(It's good to read cvs logs now and then...)

Do you want me to add this to the parser in trunk?
It shouldn't take long. Seems like casting is pretty necessary
if we're going to start using real typing.

Our JS1 translator is not recognizing calling a class as a function
to mean cast. In fact, this is only a 'convention' in JS2, you are
allowed to have calling a class as a function do anything you want.
So, Don is right, we probably want to use the cast operator, which
is named `as`.

LzView(x) is probably not recognized as a cast,
but as a normal function call. I wonder if we
should support the 'as' directive so we can
recognize and elide casts.
var ip:LzView = (this.immediateparent as LzView);
The semantics are similar, except that 'as' can return
null in cases where casts would throw an exception.
The alternative is to recognize all class names.

So the type cast "LzView(...)" is getting sent through to the
output, which must be confusing JS1.

I tracked it down to this line in LzView's construct method
var ip:LzView = LzView(this.immediateparent);
If I change that to not use type casting, it works:
//var ip = this.immediateparent;
