c++ - C++ 允许使用 "delete this"吗？

Question

是否允许 delete this; 如果 delete 语句是将在该类实例上执行的最后一条语句？当然，我确信 this 指针表示的对象是 newly-created。

我在想这样的事情:

void SomeModule::doStuff()
{
    // in the controller, "this" object of SomeModule is the "current module"
    // now, if I want to switch over to a new Module, eg:

    controller->setWorkingModule(new OtherModule());

    // since the new "OtherModule" object will take the lead, 
    // I want to get rid of this "SomeModule" object:

    delete this;
}

我可以这样做吗？

我认为这句话很好地概括了它

As long as you're careful, it's OK for an object to commit suicide (delete this).
