add type of "int" for sadd

[xxxxxxming]

I want to use int array for the arguments to sadd, then I found that it only supports strings array:

func appendArgs(dst, src []interface{}) []interface{} {	if len(src) == 1 {	if ss, ok := src[0].([]string); ok {	for _, s := range ss {	dst = append(dst, s)	}	return dst	}	}	for _, v := range src {	dst = append(dst, v)	}	return dst } 

Maybe it could be change somewhere like this?

func appendArgs(dst, src []interface{}) []interface{} {	if len(src) == 1 {	if ss, ok := src[0].([]string); ok {	for _, s := range ss {	dst = append(dst, s)	}	return dst	}	// new add	if ss, ok := src[0].([]int); ok {	for _, s := range ss {	dst = append(dst, s)	}	return dst	}	}	for _, v := range src {	dst = append(dst, v)	}	return dst }
