假設我必須實現在兩個不同的包中聲明的兩個不同的接口（在兩個不同的獨立項目中）。我在包裹里 Apackage Atype interface Doer {    Do() string}func FuncA(Doer doer) {     // Do some logic here using doer.Do() result     // The Doer interface that doer should implement,      // is the A.Doer}并在包 Bpackage Btype interface Doer {    Do() string}function FuncB(Doer doer) {    // some logic using doer.Do() result     // The Doer interface that doer should implement,      // is the B.Doer}在我的main包裹里package mainimport (    "path/to/A"    "path/to/B")type C int// this method implement both A.Doer and B.Doer but// the implementation of Do here is the one required by A !func (c C) Do() string {    return "C now Imppement both A and B"}func main() {    c := C(0)    A.FuncA(c)    B.FuncB(c) // the logic implemented by C.Do method will causes a bug here !}如何處理這種情況？
