有没有等同于Python的ChainMap的golang包？

package main

import "fmt"

type ChainMap struct {
    maps []map[string]interface{}
}

func (cm *ChainMap) Get(key string) (interface{}, bool) {
    for _, m := range cm.maps {
        value, ok := m[key]
        if ok {
            return value, true
        }
    }
    return nil, false
}

func main() {
    // 创建两个字典
    dict1 := map[string]interface{}{
        "name":  "Alice",
        "age":   25,
        "email": "alice@example.com",
    }

    dict2 := map[string]interface{}{
        "name":   "Bob",
        "age":    30,
        "gender": "male",
    }

    // 创建ChainMap
    cm := &ChainMap{
        maps: []map[string]interface{}{dict1, dict2},
    }

    // 获取键值对
    value, ok := cm.Get("name")
    if ok {
        fmt.Println(value)
    }

    value, ok = cm.Get("age")
    if ok {
        fmt.Println(value)
    }

    value, ok = cm.Get("email")
    if ok {
        fmt.Println(value)
    }
}
