Method dispatch is simplified if it doesn't need to do type matching as well.
不需要做类型匹配的方法处理是简单的。
Experience with other languages told us that having a variety of methods with the same name but different signatures was occasionally useful but that it could also be confusing and fragile in practice.
其他语言的经验告诉我们，函数名称相同，而参数不同，这种使用场景只是偶尔。但是在实践中，重载的应用是很容易令人困惑。
Matching only by name and requiring consistency in the types was a major simplifying decision in Go's type system.
在Go语言里面，函数名称的唯一性规定是为了让程序看起来简洁明了。
Regarding operator overloading, it seems more a convenience than an absolute requirement. Again, things are simpler without it.
关于运算的重载，它也不是必须不可的。同上，没有运算符的重载，程序看起来更简洁明了。
