如何通过读取设置文件在Golang中动态创建结构？

Question

I would like to create structs by reading *.yaml file and struct name, property names and their types should be set in settings file.

PERIOD: 1y
KEYSPACE: Lana
Tables:
  User:
    - UserId UUID
    - Gender String
    - Age Integer
    - Likes String
    - Income Integer
    - Children Integer

I know I should use reflection, should I? :-).

Can't you use a map[string]interface{}?

func Load(filename string) (map[string]interface{}, error) {
    data, err := ioutil.ReadFile(filename)
    if err != nil {
        return fmt.Errorf("error reading file, %s", err.Error())
    }
    var result map[string]interface{}
    err := yaml.Unmarshal(data, result)

    return result, err
}
