为什么C++变量名字和函数名字不能是同一个？

在Java中，函数名字和变量名字可以一样。

class Test {  private boolean isVal;  public boolean isVal() {      return isVal;  }}

但是在C++中是不允许这么做的，

class Test {      bool isVal() const {          return isVal;      }  private:      bool isVal;};

为啥C++不允许这样的行为呢？

You can take the address of a member:

&Test::isVal

So you can't have two members have the same name, except that you can overload member functions. Even if you could disambiguate that by some kind of cast, the next problem would already arise at other places.
