FlexBuilder's debugger will show you the "memory location" (or, I can only assume, something roughly analogous) of any in-scope instance:
But I'd like to get this information in code (sort of like Python's id function), so I could very easily trace how objects move through out the system. For example, I might have:
trace("Returning", id(foo));
Then somewhere else I could use:
trace("Using", id(foo));
To make sure both bits of code are dealing with the same instance.
Now, I know that many AS classes implement the IUID interface... But there are also a bunch of classes which don't (plain old arrays and objects, for example), so that wouldn't solve my problem.
I realize that I could also wrap objects in an ObjectProxy, but that would be less than ideal as well.
