About GetOrElse

[朱旭斌]

I think GetOrElse's implementation should like this,in actuality,the most cases want to set default value when input is zero value

func GetOrElse(v interface{}, def interface{}) interface{} {
if v == nil {
return def
}

val := reflect.ValueOf(v)
if val.Kind() == reflect.Ptr {
	val = val.Elem()
}

if val.IsZero()  {
	return def
} else if val.Kind() != reflect.Ptr {
	return v
}

return val.Elem().Interface()

}
