Anyway, I came upon a case where I needed to know the type a variable was so I could cast it properly(and for debugging), and I found that Flex doesn’t have a function to simply return a variable’s type. There is describeType(), but this returns an XML object with all of the information about the variable — not just the type. Plus you have to import the proper class to use it. So, I threw together this function quickly that will perform the import, and return/alert the type as needed:

private function getType(value:*, alert:Boolean = false):String
{
	import flash.utils.*;
	var description:XML = describeType(value);
	if(alert)
		Alert.show(description[0].@name);
	return description[0].@name;
}

I hope someone else can find it useful.
