[覚書]Goでenumっぽいので表示名を作る ref: http://qiita.com/soundTricker/items/f9d2c3e3902e8ddd4a98

enum.go

type EnumType int

const (
  One EnumType = iota //初期値を0以外にする場合は iota+1とかで調整
  Tow
  Three
)

//EnumType の文字列表現
var enumTypes = [...]string{
  "一",
  "二",
  "三",
}

//Enum→string
func (e EnumType) String() string { return enumTypes[e]}

//string→Enum こっちは微妙
func ParseEnumType(name string) EnumType {
    for i, display := range enumTypes {
        if name == display {
            return EnumType(i)
        }
    }
    return One  
}

//int → Enum は EnumType(int)とかでやるはず
