A:
There is no way to do that, and when you are working in release mode (i.e. not debuuging a swf) local variable name didn't exist anymore.
But if it's a public field name of a class you can use describeType to found the name.
package {
import flash.utils.describeType;
class Foo extends Sprite {
public var bar:Object;
function Foo(){
super();
// trace all public field name in this class
for each (variable:XML in describeType(this).variable) {
trace("field name : ", variable.@name);
}
}
}
}

yes it's a public var in a class. is a skinPart.But I heard that is heavy to rely on describeType, right?Now I have found the .id but only works when instanced

@Totty If you can specify a little bit on what you want achieve, maybe there is a solution.

"when you are working in release mode, local variable name didn't exist anymore". This is somewhat true, except there must be a lookup table to the variable names somewhere because you can access variables through string like so: this["bar"]. This does not mean YOU have access to the names though

@TandemAdam, no LOCAL VARIABLE are just compiled as an integer index representing the position of the register holding the variable, but as i said you can access public CLASS MEMBER with describeType for example. Your this["bar"] is just accessing such a field.
