Proposal: Allow methods in enums

[TheUnlocked]

Currently, it's not possible to define a method inside of an enum. This, for example, or anything like it does not compile:

public enum FooType{
  FOO,
  BAR,
  BANG,
  POW;

  public string GetName(){
    switch(this){
      case FooType.FOO:
        return "Foo";
      case FooType.BAR:
        return "Foo";
      case FooType.BANG:
        return "Foo";
      case FooType.POW:
        return "Foo";
    }
    return null;
  }
}

It is possible to emulate this effect using extensions:

public enum FooType{
  FOO,
  BAR,
  BANG,
  POW
}

public static class FooTypeExtension{
  public static string GetName(this FooType ftype){
    switch(ftype){
      case FooType.FOO:
        return "Foo";
      case FooType.BAR:
        return "Foo";
      case FooType.BANG:
        return "Foo";
      case FooType.POW:
        return "Foo";
    }
    return null;
  }
}

However, the fact that you're required to write a whole other class just to add a method to the enum seems a little big ridiculous to me. I'm not going to go as far as to suggest that an enum should be a full-fledged class (that has already been suggested in #274), but the capacity to do things which are already legal through extensions seems reasonable.

This appears to be a duplicate of #297.

You seem to be right. I guess when I searched around for this I didn't search hard enough.
