I don’t think I realized that for each can be used for normal Objects in ActionScript. I always assumed it was restricted to array-like objects to loop through the indexed values.
Like I mentioned in the JIRA here: https://issues.apache.org/jira/browse/FLEX-35070 that for-in is not a good replacement for cases where Array has custom properties or methods added to it (which happens in Javascript).
