Is there a way to define an enum in AS3 in a way we do it in other languages? I can define constants with defined values like that:

private const CONST_1:int = 0;
private const CONST_2:int = 1;
private const CONST_3:int = 2;

and so on. If I want to insert some other constant between 3 these I need to move all values like that:

private const CONST_1:int = 0;
private const CONST_2:int = 1;
private const CONST_2A:int = 2;
private const CONST_3:int = 3;

while in other language I would end up with only adding a new member to enum closure like that:

enum {
    CONST_1 = 0,
    CONST_2,
    CONST_2A,
    CONST_3
} MyConstEnum;

Does AS3 has something similar?

Thanks
