Golang で []interface{} を []string に変換するにはどうすればよいですか?

package main

import (
    "fmt"
    "strconv"
)

func main() {
    t := []interface{}{
        "zero",
        1,
        2.0,
        3.14,
        []int{4, 5},
        struct{ X, Y int }{6, 7},
    }
    fmt.Println(t)

    // Convert []interface{} to []string
    s := make([]string, len(t))
    for i, v := range t {
        switch v.(type) {
        case string:
            s[i] = v.(string)
        case int:
            s[i] = strconv.Itoa(v.(int))
        case float64:
            s[i] = strconv.FormatFloat(v.(float64), 'f', -1, 64) // customize formatting as needed
        case []int:
            s[i] = fmt.Sprintf("%v", v.([]int))
        case struct{ X, Y int }:
            s[i] = fmt.Sprintf("%v", v.(struct{ X, Y int }))
        }
    }
    fmt.Println(s)
}

[zero 1 2 3.14 [4 5] {6 7}]
[zero 1 2.000000 3.140000 [4 5] {6 7}]
