Go Lang（已标记）枚举 - 大于64b？

Question

我一直在使用“const iota”解决方案来实现类似enum的结构（参见here）。但是最近我遇到了一点SNAFU - 我的一个枚举已经达到64b的极限（我正在使用int64 consts）。任何想法，没有把自己倾注到数学/大的地狱般的下腹部？

[编辑：添加示例代码]

package testy

import (
    "fmt"
    "strings"

type testyEnum int64

    TE14
    TE15
    TE16
    TE17
    ... (list shortened)
    TE107
    TE108
    TE109
)

//HasFlag returns true if the caller has all of the flags from the parameter
func (obj testyEnum) HasFlag(right testyEnum) bool {
