Flash Hacks: Undocumented ActionScript
Overview ActionScript's basic for...in loop effectively says to the Flash interpreter, "Look at the object of interest, and for each of its properties (including its methods stored within properties), execute the body of the loop once. However, many of ActionScript's built-in methods and properties aren't enumerable within a for...in loop by default. Macromedia assumes one wants to see the objects and properties that the code creates, not the ones that underpin ActionScript, so they hid a lot of the built-in properties from being enumerated with for...in. However, the undocumented ASSetPropflags() function can make properties and methods visible even if they aren't ordinarily enumerable within a for...in loop.
