What's the best way to implement the enum idiom in Ruby? I'm looking for something which I can use (almost) like the Java/C# enums.

I made a similar question a few days ago, but now I have new requirements, and new challenges =). As usual, I'm using the animal enums for didactic purposes, once I don't want to explain domain-specific stuff
I have a basic enum of animals, which is used by the whole zoo (I can add stuff to it, but…

instead of switch statements…

public static final String OPTION_1 = "OPTION_1";
... to enums:
public enum Options {
OPTION_1;
}
With constants, you'd just refer to the constant:
String s = TheClass.OPTION_1
But with Enums, you have to specify toString():
