public const undefined:*
A special value that applies to untyped variables or dynamic object
properties that have not been initialized. The value undefined applies to
untyped variables that have not been initialized. In ActionScript 3.0 only
variables that are untyped can hold the value undefined, which is not true
in ActionScript 1.0 and ActionScript 2.0. For example, both of the following
variables are undefined because they are untyped and unitialized:
var foo;
var bar:*;
So I just assumed "undefined" was only for use with untyped and/or
unitialized dynamic vars. There's nothing here about typing as Object.
Maybe the docs have conflicting information in different places since the
recent change to undefined???
