Go에서 세 가지 값 사이의 동등성을 효율적으로 확인하는 방법은 무엇입니까?

<code class="go">if a == b && a == c {
    fmt.Println("All 3 are equal")
}</code>

<code class="go">if len(map[interface{}]int{a: 0, b: 0, c: 0}) == 1 {
    fmt.Println("Via a map set: all 3 are equal")
}</code>

<code class="go">if [2]interface{}{a, b} == [2]interface{}{b, c} {
    fmt.Println("Via arrays: all 3 are equal")
}</code>

<code class="go">if map[interface{}]bool{a: b == c}[b] {
    fmt.Println("Via a tricky map: all 3 are equal")
}</code>

<code class="go">if struct{ a, b interface{} }{a, b} == struct{ a, b interface{} }{b, c} {
    fmt.Println("Via anonymous structs: all 3 are equal")
}</code>

<code class="go">if reflect.DeepEqual([]interface{}{a, b}, []interface{}{b, c}) {
    fmt.Println("Via slices: all 3 are equal")
}</code>

<code class="go">func AllEquals(v ...interface{}) bool {
    if len(v) > 1 {
        a := v[0]
        for _, s := range v {
            if a != s {
                return false
            }
        }
    }
    return true
}</code>
